Photon switch by Fano interference in a double quantum well structure

摘要

In this paper, we demonstrate a weak photon switch by Fano interference in a double quantum well structure. GaAs/AlGaAs and InGaAs/AlAs heterostructures are taken as switch media to show that the weak switch can work at different wavelength by choosing materials and structures. We also estimate the order of the switch power and show that this photon switch by Fano interference in coupled double quantum well structures is a weak optical switch that can be used to realize one optical beam control another beam.
