Transient dual-energy lasing in a semiconductor microcavity
Feng-Kuo Hsu, Wei Xie, Yi-Shan Lee +2
We demonstrate sequential lasing at two well-separated energies in a highly photoexcited planar microcavity at room temperature. Two spatially overlapped lasing states with distinc…
Multiple-pulse lasing from an optically induced harmonic confinement in a highly photoexcited microcavity
Wei Xie, Feng-Kuo Hsu, Yi-Shan Lee +2
We report the observation of macroscopic harmonic states in an optically induced confinement in a highly photoexcited semiconductor microcavity at room temperature. The spatially p…
Spin-polarized lasing in a highly photoexcited semiconductor microcavity
Feng-kuo Hsu, Wei Xie, Yi-Shan Lee +2
We demonstrate room-temperature spin-polarized ultrafast (10 ps) lasing in a highly optically excited GaAs microcavity. This microcavity is embedded with InGaAs multiple quan…
A Room-temperature Spin-polarized Polariton Laser
Feng-kuo Hsu, Yi-Shan Lee, Sheng-Di Lin +1
In the field of spin-controlled semiconductor lasers, massive effort has been focused upon materials with long spin relaxation times (~ns). In contrast, we demonstrate room-tempera…
Angle-Resolved Spectroscopy of Parametric Fluorescence
Feng-kuo Hsu, Chih-Wei Lai
The parametric fluorescence from a nonlinear crystal forms a conical radiation pattern. We measure the angular and spectral distributions of parametric fluorescence in a beta-bariu…
