The leakage current, avalanche gain, excess noise and frequency response of InAs avalanche photodiodes (APDs) were investigated. Despite having a narrow bandgap, InAs APDs, which were fabricated using optimized fabrication procedures and surface passivation technique, were able to provide reasonably...
