Abstract
A method of generating high power optical signals in the 1-100 GHz frequency range uses a frequency modulated semiconductor laser and an interferometer. This method is especially useful for microwave carrier frequency optical communications, distribution of microwave frequency local oscillator signals, and the generation of sinusoidal optical modulation at frequencies that cannot be reached by direct modulation in semiconductor lasers or with external module lasers.
