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,

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

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 ...

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.

Tunable Plasmonic Nanolaser Based on Graphene

Plasmonics, 2018
Surface plasmon polariton nanolaser, which can achieve all-optical circuits and optoelectronic integration, is a major research area in nano-optics. We propose a novel tunable nanolaser that combines graphene and traditional metal–dielectric waveguide.

Intracavity Spectroscopy and Sensorics with Plasmonic Nanolaser

2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019
In laser physics, intracavity laser spectroscopy methods are known to have an extremely high sensitivity [1]. In these methods, an analyte being detected that absorbs at the lasing wavelength is placed in the laser cavity. The analyte is then detected by changing the lasing parameters, such as the threshold, intensity, and wavelength, resulting in the ...

Plasmon nanolaser: current state and prospects

Physics-Uspekhi, 2017
In the last two decades, extensive research has been devoted to the development of new ultra-small lasers. The greatest progress has been made with semiconductor lasers. A fundamentally new approach to the miniaturization of lasers is based on using plasmon instead of photon fields. This review is devoted to an interesting and rapidly developing field,

Nanolasers based on nanowires and surface plasmons

SPIE Newsroom, 2009
Development of nanolasers has been an active area of research for quite a number of years. The overall goal is to make lasers as small as possible or—more quantitatively, as a Defense Advanced Research Projects Agency program1 challenges—to produce a laser that is smaller than a single wavelength in all three spatial dimensions.
