ABSTRACT:
Methods of and apparatus for measuring the frequency response of optical detectors based on interferometrically demodulating a frequency modulated semiconductor laser. Detectors can be characterized where the 3 dB roll-off frequency is in excess of 100 GHz, is self-calibrating by simplified and inexpensive techniques.
