METHOD FOR RECEIVING OPTICAL PULSES Russian patent published in 2022 - IPC G01R19/175 H01L31/107 

FIELD: optical technology.

SUBSTANCE: invention relates to the reception of optical signals using avalanche photodiodes and can be used in location, communication and other photoelectronic systems. The method for receiving optical pulses using an avalanche photodiode includes threshold signal processing and the formation of output pulses using a threshold device when the signal from the output of the photodiode exceeds the specified threshold of operation, the avalanche mode is adjusted at the temperature point T = T₀, the most critical to the specified operating conditions, and the course of the temperature dependence of the bias voltage is formed as follows, in order for the avalanche multiplication coefficient of the photodiode to meet the specified requirements for the gain coefficient of the receiving path, taking into account the permissible frequency of microplasma breakdowns in the entire operating temperature range, including the point T = T₀, while the avalanche multiplication coefficient M at the temperature point T = T₀ should be as close as possible to the optimal value where Q is a constant coefficient independent of temperature and set during adjustment.

EFFECT: ensuring sensitivity close to the maximum achievable in all modes, including in the presence of microplasma breakdowns.
