Paper Abstract

The modulation in a multiple quantum well (MQW) element depends on the magnitude of the signal charge transported in the heterostructure acoustic charge transport (HACT) channel adjacent to the MQW layers that host the excitons. The signal charge is introduced in the HACT channel by optical injection, and is proportional to the light intensity. This charge is swept by a SAW beam launched by the transducer located on one side of the HACT channels. This system allow the transformation of electronic data into optical signals via acoustic waves.
