6:05 to 6:35 pm: Attosecond pulses generated in gases and solids

Paul B. Corkum, Univ. of Ottawa and National Research Council of Canada (Canada)
2018 Winner of the SPIE Gold Medal Award in recognition of his conceptual contributions and the development of new laser methods that have led to the creation of the field of attoscience.

Attosecond pulses are generated by electrons that are extracted from a quantum system by an intense light pulse and travel through the continuum under the influence of the electric field of the light. Portions of each electron wave packet are forced to re-collide with its parent ion after the field reverses direction. Upon re-collision, the electron and ion can recombine, emitting soft x-ray radiation that can be in the form of attosecond pulses. This highly nonlinear process occurs in atoms, molecules and solids and offers unique measurement opportunities – for measuring the attosecond pulse itself; the orbital(s) from which it emerged; and the band structure of material in which the wave packets moved.

Paul Corkum is a Fellow of the Royal Societies of Canada and London; a foreign member of the US, the Austrian and the Russian Academy of Science. In 2013, he was awarded Saudi Arabia’s King Faisal Prize for science and Israel’s Harvey Prize for physics. In 2014 he was named “Thompson Reuters Citation Laureate for work that is of Nobel class and likely to earn the Nobel someday”.


6:35 to 7:05 pm: Metasurface Flat Optics: Unifying Semiconductor Manufacturing and Lens Making

Federico Capasso, John A. Paulson School of Engineering and Applied Sciences, Harvard Univ. (United States)

Metasurfaces provide a new basis for recasting optical components into thin planar elements, easy to optically align and control aberrations, leading to a major reduction in footprint, system complexity and cost as well as the introduction of new optical functions.1, 2, 3. Their planarity allows for fabrication routes directly in line with conventional processes of the mature integrated circuit (IC) industry.1 I foresee great technological and scientific penetration of CMOS compatible metasurface-based optical components, ranging from metalenses4-6 to novel polarization optics7, 8. Camera modules for high volume applications, such as cell phones, will be the greatest beneficiaries. The technology required to mass produce metasurfaces dates back to the early 1990s, when the feature sizes of semiconductor manufacturing became smaller than the wavelength of light, advancing in stride with Moore’s law. This provides the possibility of unifying two industries: semiconductor manufacturing and lens-making, whereby the same technology used to make computer chips is used to make metalenses and other optical components, based on metasurfaces. A major obstacle for this to happen had to be overcome. With metasurfaces, the data describing large designs are faced with the challenge of enormous file sizes due to having millions or billions of individual microscopic metaelements (necessitated by the subwavelength size criterion) described over macroscopically large device areas. This extremely high data density over large areas generates unmanageably large total file sizes, limiting the fabrication of optical components such as metalenses to sizes no larger than a few millimeters. Using our new scalable metasurface layout compression algorithm (METAC) that exponentially reduces design file sizes (by 3 orders of magnitude for a centimeter diameter lens) and stepper photolithography, we have recently shown the design and fabrication of metalenses with extremely large areas, up to centimeters in diameter and beyond.9 Finally I envision a future of digital optics based on metasurfaces with increased density of optical components and functionalities per metasurface; it is tempting to speculate that an empirical law might govern its growth, akin to Moore’s Law for digital electronics.

Prof. Federico Capasso is the recipient of numerous awards, including the SPIE Gold Medal in 2013 in recognition of his seminal and wide-ranging contributions to photonics; in particular bandgap engineering of optoelectronic materials and devices, quantum cascade lasers and plasmonics based photonic devices.

A unifying theme of Prof. Capasso's research is the quantum design and study of new artificial materials and nanostructures with man-made electronic and optical properties, an approach that Prof. Capasso pioneered and dubbed bandstructure engineering. These structures are grown by thin film deposition techniques such as Molecular Beam Epitaxy (MBE). These studies include both the investigation of quantum effects in lower dimensionality systems and the invention of photonic and electronic devices in which quantum effects on a mesoscopic scale (a few to ~ 100 nm) play a dominant role. This multi-faceted research led Capasso and his collaborators to invent the quantum cascade (QC) laser, a fundamentally new light source whose emission wavelength can be designed to cover the entire spectrum from the mid to the far infrared by tailoring the active region layer thickness. QC lasers are now commercially available and have wide ranging applications to molecular spectroscopy, chemical sensing and trace gas analysis (such as atmospheric chemistry, combustion diagnostics, breath analyzers in medicine, pollution monitoring and industrial process control, homeland security) and telecommunications.

Plenary Presentations:

8:30 to 9:15 am: Plasmonic Nanostructures for Molecular Sensing and Actuation

Mikael Käll, Chalmers Univ. of Technology (Sweden)

The prospect of ultrasensitive, rapid, and cost-effective molecular analysis has been one of the main drivers behind the rapidly evolving field of plasmonics. I will illustrate this development by describing several recent molecular sensing and actuation experiments that are all based on the extremely efficient conversion of light from the far-field to or from the near-field by virtue of plasmon excitation in metal nanostructures. The examples utilize different kinds of molecular contrast (fluorescence, Raman scattering, refractive index, viscosity) as well as plasmon-enhanced thermal and optical forces for diverse applications, including controlled DNA release, detection of nerve gases, and studies of molecular interactions at the single molecule limit.

Mikael Käll is Professor of physics and Wallenberg Scholar at Chalmers University of Technology. In the late 1990’s, after PhD and post doc research on superconductivity, he switched to the field of nanooptics, where he has since contributed over 150 papers on diverse topics such as surface-enhanced Raman scattering, nanoplasmonic sensors, and optical manipulation of metal nanoparticles.

9:15 to 10:00 am: Rapidly Time-Variant Metadevices for Linear Frequency Conversion

Bumki Min, KAIST (Korea, Republic of)

Energy conversion in a physical system requires time-translation invariance breaking according to Noether's theorem. Closely associated with this symmetry-conservation relation, the frequencies of electromagnetic waves are found to be converted as the waves propagate through a temporally varying medium. Thus, effective temporal control of the medium, be it artificial or natural, through which the waves are propagating, lies at the heart of linear frequency conversion. Here, we explain the basic principle of linear frequency conversion in a rapidly time-variant metadevice and show various interesting properties and future prospects of rapidly time-variant metadevices.

Bumki Min received B.S. and M.S. degrees in Electrical Engineering from Seoul National University in 1999 and 2001, and M.S. and Ph.D. degrees in Applied Physics from Caltech in 2003 and 2006, respectively. After graduation, he worked as a postdoctoral scholar at Caltech and UC Berkeley. He is currently an associate professor in the department of Mechanical Engineering at KAIST. His main research interests include metamaterials and micro/nanophotonics.

Coffee Break 10:00 to 10:30 am

10:30 to 11:15 am: Structured Light on the Nanoscale

Natalia M. Litchinitser, Univ. at Buffalo (United States)

Structured light and structured matter are two fascinating branches of modern optics that recently started having a significant impact on each other. The synergy of complex beams, such as the beams carrying an orbital angular momentum, with nanostructured engineered media is likely to bring new dimensions to the science and applications of structured light, ranging from fundamentally new regimes of spin-orbit interaction to novel ways of information encoding for the future optical communication systems. We will discuss fundamental optical phenomena at the interface of singular and nonlinear optics in engineered optical media and show that the unique optical properties of optical nanostructures open unlimited prospects to “engineer” light itself.

Natalia Litchinitser is currently a Professor of Electrical Engineering at University at Buffalo, The State University of New York and will be joining Electrical and Computer Engineering Department at Duke University in August 2018. Her group research focuses on fundamental properties and applications structured light in engineered nanostructures, biomedical imaging, optical communications and nonlinear optics. She is a Fellow of the Optical Society of America and of the American Physical Society.

11:15 am to 12:00 pm: Wave Control with "Time Materials"

Mathias Fink, Institut Langevin Ondes et Images (France)

Because time and space play a similar role in wave propagation, wave propagation is affected by spatial modulation or by time modulation of the refractive index. Here we emphasize the role of time modulation. We show that sudden changes of the medium properties generate instant wave sources that emerge instantaneously from the entire wavefield and can be used to control wavefield and to revisit the way to create time-reversed waves. Experimental demonstrations of this approach will be presented. More sophisticated time manipulations can also be studied and extension of these concepts in the field of plasmonics will be presented.

Mathias Fink is the George Charpak Professor at ESPCI Paris. He is member of the French Academy of Science. His area of research is concerned with the propagation of waves in complex media and the development of numerous instruments based on this basic research. 6 start-up companies with more than 300 employees have been created from his research (Echosens, Sensitive Object, Supersonic Imagine, Time Reversal Communications, Cardiawave and Greenerwave).

10:30 to 11:15 am: Making Smart Windows Smarter

Yueh-Lin (Lynn) Loo, Princeton Univ. (United States)

Heating, cooling, and lighting for buildings represent 40 percent of our nation’s energy consumption. Smart windows can reduce energy needs by up to 40 percent by regulating the transmission of visible and near-infrared light. This talk will highlight a self-powered smart-window technology that uses UV-harvesting organic solar cells for onboard power. Highlighted in the Wall Street Journal, implementation of such smart windows can simultaneously provide energy savings and increase occupant comfort.

11:15 am to 12:00 pm: Liquid Crystal Plus Polymer = Dynamic Thin Film Optical Elements

Timothy J. Bunning, Air Force Research Lab. (United States)

The use of liquid crystals to modulate light in typical devices is rooted in their ability to be patterned through the thickness of a cell via surface interactions and their susceptibility to applied fields. Recent advances in patterning the director field across the in-plane direction and the development of new materials (novel reactive mesogenic materials and photosensitive molecules) has enabled a new breed of dynamic photonic elements. This talk will explore a variety of these constructs including passive and dynamic cycloidal diffractive waveplates, switchable lenses, beamsteering structures, and dynamic mesoscopic chiral structures. Thin films which can be modulated by both light and e-field will be examined.

Dr. Timothy J. Bunning is the Chief Scientist of the Materials and Manufacturing Directorate, Air Force Research Laboratory, Wright-Patterson Air Force Base, Ohio.
