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

Photorefractive Multiple Quantum Well Waveguide as a Bragg Reflector

An interaction between the signal wave propagating in a planar waveguide and a photorefractive grating is analysed. The waveguide contains an AlGaAs/GaAs multiple quantum well guiding layer biased with an external electric field applied along the wells plane. The grating is formed by two external beams interfering in the multiple quantum well layer. The dependence of the steady-state grating properties on the external waves parameters and applied electric field intensity is presented. Possible application of the grating as an optically controlled Bragg reflector with memory is analysed
