Impact of Cavity Geometry on Microlaser Dynamics
Physical Review Letters, 2023 We experimentally investigate spatio-temporal lasing dynamics in semiconductor microcavities with various geometries, featuring integrable or chaotic ray dynamics. The classical ray dynamics directly impacts the lasing dynamics, which is primarily determined by the local directionality of long-lived ray trajectories.

CHAOTIC MICROLASERS BASED ON DYNAMICAL LOCALIZATION [PDF]
International Journal of Bifurcation and Chaos, 2004 We report the first direct observation of lasing action from a dynamically localized mode in a microdisk resonator with rough boundary. In contrast to microlasers based on stable ray trajectories, the performance of our device is robust with respect to the boundary roughness and corresponding ray chaos, taking advantage of Anderson localization in ...

Gold nanorod plasmonic upconversion microlaser [PDF]
14th IEEE International Conference on Nanotechnology, 2013 Plasmonic-photonic interactions have stimulated significant interdisciplinary interest, leading to rapid innovations in solar design and biosensors. However, the development of an optically pumped plasmonic laser has failed to keep pace due to the difficulty of integrating a plasmonic gain material with a suitable pump source.

Controlling the gain contribution of background emitters in few-quantum-dot microlasers
New Journal of Physics, 2018 We provide experimental and theoretical insight into single-emitter lasing effects in a quantum dot (QD)-microlaser under controlled variation of background gain provided by off-resonant discrete gain centers.
