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…
Mobility modulation effects in a double quantum well infrared photon-detector
Ting-Ting Kang, Susumu Komiyama, Takeji Ueda +2
An electrically isolated quantum well (QW) island can be positively charged by incoming infrared photon, because its electrons absorb photon energy via intersubband transition and…
Probing onset of strong localization and electron-electron interactions with the presence of direct insulator-quantum Hall transition
Shun-Tsung Lo, Kuang Yao Chen, T. L. Lin +11
We have performed low-temperature transport measurements on a disordered two-dimensional electron system (2DES). Features of the strong localization leading to the quantum Hall eff…
