Abstract
The gain of a light detector built around a germanium LFD-2A photodiod e is controlled by automatically adjusting the diode bias so as to hav e a constant delay between the pulses generated by two comparators wit h different thresholds connected to the photodiode output. When detect ing optical pulses generated by a GaAlAs injection laser varying over a dynamic range of 20 : 1, the output signal instability is less than 5%, and the delay jitter is less than 350 psec.
