AbstractThe electro-absorption of AlGaAs/GaAs diffused quantum well (DFQW) modulator using surface acoustic wave (SAW) QW interactions was studied theoretically. The modulator was also optimized through the use of both the steeper potential at the device surface for modulation and a long λSAW and a low power SAW. The non-uniform feature of the SAW induced potential was also taken into account in optimizing the device structure. Interdiffusion took place into the W stack to modify modulation performance so that λop and the optical properties of the optimized structure can be further modified. The modulation efficiency of an incident optical field depended on the guiding properties in the QW active region.
