Abstract :
A new optical heterodyne detector, consisting of a silicon photodiode and an integrated diffraction grating on the diode surface, is proposed and its successful operation is demonstrated. The detector is shown to be compact in structure and quite stable to mechanical misalignment with respect to incident optical waves.
