Abstract

The model of non-stationary multiplication process in Avalanche semiconductor structure with Negative Feedback (ANF) is presented. Simulated dependencies of multiplication probability distribution, noisefactor and character avalanche rise time illustrate the main features ofANF process. Some experimental resuits, obtained on a laboratory Si-based ANF device samples, are found to be in good agreement with the model predictions, and demonstrate high threshold characteristics of such devices. A unique combination of high gain, low noise, fast response and high quantum efficiency is shown to allow an analog detection of few-photon short light pulses -thetask, unsolved up to present time. Opportunities of creation of matrix devices and devices, based on non-silicon semiconductors and intended for other spectral ranges are also considered as well as the prospects of their use in free space laser communication.
