Abstract:
1. A clock generator for generating a clock signal from laser light, the clock generator comprising: an interferometer having a dual optical output and an input, the interferometer receiving laser light at the input and the interferometer having an optical imbalance; a first photodetector and a second photodetector, each photodetector in optical communication with a respective one of the dual optical outputs of the interferometer, and each photodetector having an output; a multiplier having an output and having a first input in electrical communication with the output of the first photodetector and second input in electrical communication with the output of the second photodetector; a zero-crossing detector having an electrical input in electrical communication with the output of the multiplier, the output of the zero-crossing detector being the generated clock signal.
