Investigation of the Two-Mode Operation of Avalanche Photodiodes in the Registration of Optical Radiation

Resumo

The possibility of the simultaneous operation of avalanche photodiodes in the photon-counting and current modes is shown. The double-mode operation is provided at a constant supply voltage of an avalanche photodiode that exceeds the breakdown voltage of its p–n junction. The probability of the formation of microplasma pulses as a function of the intensity of optical radiation and the supply voltage of the avalanche photodiode is estimated for the considered operating mode.
