Abstract

A systematic study is presented of a multiple-quantum-well (MQW) acousto-optic modulator. The device utilises the electro-absorptive effects in quantum wells and the electric field induced by surface acoustic waves (SAW). The propagation of SAW in multilayered piezoelectric structures is studied and the electric field is calculated. The optical absorption coefficient in a MQW is calculated as a function of the applied electric field and the MQW parameters. A systematic approach for optimising the performance of a MQW acousto-optic modulator is presented
