Suppression of absorption by quantum interference in intersubband transitions of tunnel-coupled double quantum wells
Wen-Xing Yang, Jin Xu, Ray-Kuang Lee
We propose and analyze an efficient scheme for suppressing the absorption of a weak probe field based on intersubband transitions in a four-level asymmetric coupled-quantum well (C…
Slow optical solitons via intersubband transitions in a semiconductor quantum well
Wen-Xing Yang, Ray-Kuang Lee
We show the formation of bright and dark slow optical solitons based on intersubband transitions in a semiconductor quantum well (SQW). Using the coupled Schrodinger-Maxwell approa…
Direct observation of higher-order whispering-gallery modes in VCSELs at room temperature by embedding a defect-free surface micro-structure
Tsin-Dong Lee, Chih-Yao Chen, YuanYao Lin +5
We propose and demonstrate a direct method to observe higher-order whispering-gallery modes in vertical cavity surface emitting lasers (VCSELs) at room temperature. Instead of intr…
A Simple Model for Cavity Enhanced Slow Lights in Vertical Cavity Surface Emission Lasers
Chia-Sheng Chou, Ray-Kuang Lee, Peng-Chun Peng +4
We develop a simple model for the slow lights in Vertical Cavity Surface Emission Lasers (VCSELs), with the combination of cavity and population pulsation effects. The dependences…
Soliton transverse instabilities in nonlocal nonlinear media
YuanYao Lin, Ray-Kuang Lee, Yuri S. Kivshar
We analyze the transverse instabilities of spatial bright solitons in nonlocal nonlinear media, both analytically and numerically. We demonstrate that the nonlocal nonlinear respon…
