Abstract :
The authors report a photodetector array based on an amorphous silicon-germanium alloy thin film. The detector array is designed for detecting light pulses from (Ga,Al)As laser diodes. An experimental 2*2 detector array, addressed by a silicon shift register, works to a clock frequency of 25 MHz and shows good stability.<>
