A new class of photonic-crystal fiber with a hollow core and various lattice modifications may be an important component for biosensing applications.

Room-temperature lasing in cavities with a mode volume of 0.017μm³ and a high quality factor is achievable.

Oblique-angle deposition, an industrial workhorse technique, has been used to deposit silver thin films that should refract negatively in the visible regime.

Sub-Angstrom-resolution sensing of tiny cantilevers is leading the way to a gentle physical probe for surfaces of materials such as living cells.

Harnessing the oscillation of electrons on conductor surfaces can effectively enhance the performance of organic photovoltaic cells.
