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

Nanophotonics, 2012
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 half ...

Polariton lasing in Mie-resonant perovskite nanocavity

Opto-Electronic Advances
Deeply subwavelength lasers (or nanolasers) are highly demanded for compact on-chip bioimaging and sensing at the nanoscale. One of the main obstacles for the development of single-particle nanolasers with all three dimensions shorter than the emitting ...

All-dielectric nanolaser

, 2014
We demonstrate theoretically that a subwavelength spherical dielectric nanoparticle coated with a gain shell forms a nanolaser. Lasing modes of such a nanolaser are associated with the Mie resonances of the nanoparticle. We establish a general condition for the lasing threshold and show that the use of high refractive index dielectric media allows for ...

Plasmonics Meets Metasurfaces: A Vision for Next Generation Planar Optical Systems

Micromachines
Plasmonics and metasurfaces (MSs) have emerged as two of the most influential platforms for manipulating light at the nanoscale, each offering complementary strengths that challenge the limits of conventional optical design.

Phase-Conjugate Feedback Effects in Electrically Pumped Semiconductor Nano-Laser Arrays

Photonics
An analysis is performed of the response of arrays of semiconductor nano-lasers to phase-conjugate optical feedback. A comparison is made of their response to conventional mirror feedback.
