Multiple Quantum Well Directional Coupler With Photorefractive Grating
We analyse an asymmetric directional coupler with a thin photorefractive grating as a switching and demultiplexing element with memory. The grating is induced by two external beams interfering in the structure of AlGaAs/GaAs multiple quantum wells with an electric field applied along the quantum well planes.
