Abstract

Synthetically modulated structures offer the capability of tunability of bandgap and other material parameters. In particular, the GaAs/AlGaAs and Ino.53Ga0.47As/ Ino.52A10.48^As systems offer these advantages in the infrared and optical communication wavelength ranges. We report here the properties of superlattices and the properties of avalanche and p-i-n photodiodes made with thes materials. The multiquantum well struc-tures (MQW) have L_Z and L_B varying from 25-500Å. Impact ionization phenomena in the different structures have also been determined from carrier multiplication and noise measurements and have been analyzed by Monte Carlo techniques. Techniques for obtaining enhanced optical absorption in very high-speed photodiodes are demonstrated.
