Abstract
The analysis of constructive and technological restrictions in design of the avalanche photo diodes, working in a photon-counting mode
Theoretical analysis of constructive and technological restrictions in the avalanche photodiode structure for photon-counting mode is made in this work. It is shown that critical parameters are load resistance and a time constant of a photodiode internal capacity recharge. For decreasing this time constant one needs size restriction of separate section of the photodiode and association of several such sections on a crystal together with registration schemes.
