Abstract
Intracavity tunneling induced transparency in asymmetric double-quantum wells embedded in a microcavity in the ultrastrong-coupling regime is investigated by the input-output theory developed by Ciuti and Carusotto. In this system a narrow spectra can be realized under anti-resonant terms of the external dissipation. Fano-interference asymmetric line profile is found in the absorption spectra.
Highlights
Intersubband electronic transitions in doped semiconductor quantum wells play an important role in many remarkable devices, such as quantum cascade lasers, quantum-well infrared photodetectors and ultrafast optical modulators [1]
If semiconductor quantum wells in a microcavity were explored by using the intersubband transitions, it can achieve an ultrastrong light-matter coupling regime where vacuum Rabi frequency becomes comparable to the intersubband electronic transitions [2]
The intersubband electronic transition in doped semiconductor quantum wells embedded in a microcavity provide a chance to discuss and test the problem
