Abstract

Surface-normal photodiodes are commonly illuminated with spot sizes smaller than the diode mesas to prevent the optical power loss and slow diffusion tail that occur when the photodiodes are overfilled. It is, therefore, critical to understand p-i-n photodetector response to highpower, small spot size optical inputs, particularly because field bleaching due to photogenerated carrier separation can significantly degrade detector response.
