Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.

Quantum theory of a spaser-based nanolaser

Optics Express, 2014
We present a quantum theory of a spaser-based nanolaser, under the bad-cavity approximation. We find first- and second-order correlation functions $g^{(1)} (τ)$ and $g^{(2)}(τ)$ below and above the generation threshold, and obtain the average number of plasmons in the cavity. The latter is shown to be of the order of unity near the generation threshold,

Photonic Crystal Nanolaser Biosensors

IEICE Transactions on Electronics, 2012
High-performance and low-cost sensors are critical devices for high-throughput analyses of bio-samples in medical diagnoses and life sciences. In this paper, we demonstrate photonic crystal nanolaser sensor, which detects the adsorption of biomolecules from the lasing wavelength shift.

Thresholdless quantum dot nanolaser

Optics Express, 2017
Thresholdless lasing is an outstanding challenge in laser science and is achievable only in devices having near unity quantum efficiency even when not lasing. Such lasers are expected to exhibit featureless linear light output curves. However, such thresholdless behavior hinders identification of the laser transition, triggering a long-lasting argument
