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 …

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 …

Optical Yagi-Uda nanoantennas

Optical Yagi-Uda nanoantennas

Conventional antennas, which are widely employed to transmit radio and TV signals, can be used at optical frequencies as long as they are shrunk to nanometer-size dimensions. Optical nanoantennas made of metallic or high-permittivity dielectric …
