Research on Materials and Components for Opto-Electronic Signal Processing and Computing

Abstract

Electro-absorption and electro-refraction properties of heterostructures and multiple quantum-well structures in GaInAs/GaAs were demonstrated and optimized for spatial light modulation applications. Techniques to generate and to confine dislocations near the substrate interface to grow a large number of strained quantum wells have been developed. Modulation at 1.06 micron wavelength were observed using strained layer quantum wells. Optical optical interaction in a multiple quantum well detector modulator pair has been demonstrated. A new device, the gate controlled photo-diode has been conceived and demonstrated.
