Ultrasmall InGaP dielectric and plasmonic nanolasers

Frontiers in Optics + Laser Science 2023 (FiO, LS), 2023
We 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, 2007
We 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.

Control by design in plasmonic nanolasers

Active Photonic Platforms XII, 2020
Plasmon-based lasers and surface plasmon amplified spontaneous emission of radiation devices (spasers) have garnered significant attention since their prediction over a decade ago. Major advances have included subwavelength footprint sizes, room-temperature operation, far-field emission directionality, and understanding of the lasing mechanism. Notably,

Diffraction-Unlimited Plasmonic Nanolaser

2014
Up to now, significantly reducing the size of semiconductor lasers in all three dimensions is the ultimate challenge for the development of nanolasers, which is a key component for long-waited on-chip optical communications and computing systems. However, the minimum size of conventional semiconductor lasers utilizing dielectric resonators is governed ...

Semiconductor plasmonic nanolasers: current status and perspectives

Reports on Progress in Physics, 2016
Scaling 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 ...

Stopped-light nanolasing in hybrid plasmonic waveguides

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
We report stopped-light nanolasing in active planar plasmonic waveguides at near-infrared frequencies. Studying its spatial, temporal and spectral signatures we reveal that, in the absence of cavity-induced feedback, the subwavelength lasing mode forms dynamically as a phased-locked superposition of quasi dispersion-free waveguide modes. This mechanism

On-Chip Monolithically Fabricated Plasmonic-Waveguide Nanolaser

Nano Letters, 2018
Plasmonic-waveguide lasers, which exhibit subdiffraction limit lasing and light propagation, are promising for the next-generation of nanophotonic devices in computation, communication, and biosensing. Plasmonic lasers supporting waveguide modes are often based on nanowires grown with bottom-up techniques that need to be transferred and aligned for use

Plasmonic Bowtie Antenna Nanolaser

2014
Abstract : The overarching goal of the NACHOS program is to demonstrate semiconductor lasers that have volume sizes no larger than the cubic of the wavelength in vacuum and can operate at room temperature under electrical injection in continuous-wave mode. Our team has successfully achieved this goal using the semiconductor-metal core-shell design.
