Since the advent of room temperature laser diodes and low loss optical fibers, photonics research, driven by the rational design of optical confinement and heterogeneous material structures, as well as by the ever expanding use of quantum effects …

How small can “Nano” be in a “Nanolaser”?

How small can “Nano” be in a “Nanolaser”?

We show that the lasing threshold of the single mode metal-semiconductor nano-laser (spaser) is determined only by the photon absorption rate in the metal and exhibits very weak dependence on the composition, shape, size (as long as it is less than …

Low loss hollow-core waveguide on a silicon substrate

Low loss hollow-core waveguide on a silicon substrate

Optical-fiber-based, hollow-core waveguides (HCWs) have opened up many new applications in laser surgery, gas sensors, and non-linear optics. Chip-scale HCWs are desirable because they are compact, light-weight and can be integrated with other …
