AlGaAsSb Avalanche Photodiodes
2018 IEEE Photonics Conference (IPC), 2018 Avalanche photodiodes are widely used in optical receivers for high-speed communication systems. We have been studying the material AlGaAsSb (lattice-matched to InP substrates) experimentally in recent years, evaluating its potential as an alternative avalanche material for these avalanche photodiodes. Our experimental studies cover key characteristics

Photodiode Circuits for Retinal Prostheses
IEEE Transactions on Biomedical Circuits and Systems, 2011 Photodiode circuits show promise for the development of high-resolution retinal prostheses. While several of these systems have been constructed and some even implanted in humans, existing descriptions of the complex optoelectronic interaction between light, photodiode, and the electrode/electrolyte load are limited.
