Novel In-Plane Semiconductor Lasers XXIII

High-quality, in-plane semiconductor lasers exhibit improved performance over a wide range of emission wavelengths from ultraviolet into the THz range. Devices are finding an ever-increasing number of applications in, for example, telecommunications, spectroscopy, displays, quantum information, and medical diagnostics and therapy. Well-developed GaAs- and InP-based lasers operating from the 0.8 to 2-μm are achieving multi-watt output powers with beams of high spatial and spectral purity. Lasers made from material systems, such as dilute nitride-antimonides or quantum-dot or nanowire active regions, are pushing performance and spectral coverage. Mode-locked diode lasers are demonstrating improvements such as reduced pulse length and timing jitter. Applications in communication are pushing advances in laser dynamics, including the use of coupled and/or chaotic semiconductor lasers. The GaN based laser field continues to innovate and make progress in terms of e.g. power, reliability and to extend operation deeper into the red and the ultraviolet parts of the spectrum. In the infrared, Sb-based quantum well lasers display high performance at wavelengths up to ~ 5 μm, and quantum cascade lasers operate at wavelengths from just below 3 μm to almost 300 μm. Emerging applications in the mid/far-infrared stimulate the development of high-efficiency, high-power quantum cascade lasers operating at an ambient temperature and with new functionalities such as ultrashort pulse generation, frequency combs, injection locking, and beam control. Novel laser sources utilize recent advances in plasmonics, nanophotonics, topological photonics, and nonlinear optics for efficient generation and manipulation of light. A variety of approaches for silicon-based lasers, including hybrid structures by local area growth or wafer bonding are yielding advancing performance. Laser sources based on novel two-dimensional and topological materials are showing promise. This conference provides a forum for the most recent breakthroughs in device design and performance, including energy efficiency. We solicit papers describing novel designs that achieve higher performance levels and unique operational characteristics, as well as papers describing the technical limitations of the current in-plane laser technology and lasers tailored to particular applications such as lidar or neuromorphic computing or for quantum applications. We are interested in new methods of fabrication or new methods of characterization that are necessary for improved performance. Papers of experimental and/or theoretical nature are welcome.
