Abstract
GaAs electroabsorption avalanche photodiodes in n‐n+ GaAs waveguides have been used to detect the 1.06‐μm radiation from a Nd : YAG laser with a responsivity of 125 A/W and an internal quantum efficiency of 23%. The response at this wavelength is due to a combination of band‐to‐band and defect‐to‐band electroabsorption.Keywords
