ABSTRACT:
An integrated optical device is disclosed which includes an integral photodetector exhibiting picosecond response times and quantum efficiences greater than about 30 percent. The photodetector includes a region of substantially amorphous semiconductor material interposed between two electrodes, with the electrode spacing being comparable to the average electron trapping length in the material between the electrodes. Preferably, at least one of the electrodes is a microstrip transmission line.
