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…

Giant Kerr nonlinearities and slow optical solitons in coupled double quantum-wells
Wen-Xing Yang, Ray-Kuang Lee
We show the formation of slow optical solitons in the asymmetric coupled double quantum-wells (CQW) via a two-photon Raman resonance. With the consideration of real parameters in A…
