Spasers, and plasmonic nanolasers
2022Abstract Surface plasmon amplification by stimulated emission of radiation (SPASER) produces emitters called a spaser for localized surface plasmon polariton (SPP) and a plasmonic nanolaser for propagating SPPs. This chapter introduces the first proposal for a spaser and its theory of amplification, and a simplified model for a spaser ...

ISLC 2012 International Semiconductor Laser Conference, 2012
We will review our works on plasmon lasers and circuits. The scaling down of laser will experience ever-increasing radiation loss and stronger divergence. Plasmonics has emerged as one solution for these hurdles.

Semiconductor plasmonic nanolasers
Numerical Simulation of Optoelectronic Devices, 2010We present recent results on modeling, fabrication, and characterization of semiconductor nanolasers based on semiconductor-metal core-shell waveguides. In particular, results of lasers with a sub-diffraction-limit thickness will be presented under electrical injection.

Printed Plasmonic GaAs Nanolasers
Conference on Lasers and Electro-Optics, 2016We present optically-pumped plasmonic GaAs nanolasers operating at room temperature. Built on suspended GaAs membranes, the etchless fabrication involves only a printed metal film, which defines the plasmonic cavity and confines the optical mode.

Ultrasmall InGaP dielectric and plasmonic nanolasers
Frontiers in Optics + Laser Science 2023 (FiO, LS), 2023We demonstrate single-mode InGaP and InGaAsP nanolasers using disk-on-pillar and disk-on-gold structures (360 nm in diameter). Silica-coated nanolaser particles produce stable sub-nanometer emission across 80 nm bandwidth (635 to 715 nm) from within biological cells.

Metamaterial Comprising Plasmonic Nanolasers
PIERS Online, 2007We consider plasmonic nanoantennas immersed in active host medium. Speciflcally shaped metal nanoantennas can exhibit strong magnetic properties in the optical spectral range due to the excitation of magnetic plasmon resonance. We propose plasmonic nanolaser, where the metal nanoantenna operates like a resonator.

Semiconductor plasmonic nanolasers: current status and perspectives
Reports on Progress in Physics, 2016Scaling down semiconductor lasers in all three dimensions holds the key to the development of compact, low-threshold, and ultrafast coherent light sources, as well as integrated optoelectronic and plasmonic circuits. However, the minimum size of conventional semiconductor lasers utilizing dielectric cavity resonators (photonic cavities) is limited by ...
