Abstract

This paper presents the concept and analysis of an all optical divide-by-2n microwave frequency divider. It uses a Mach-Zehnder light intensity modulator with 100% modulation IM index which is utilized to generate a subharmonic optical sideband. This optical sideband when mixed with the optical carrier in a photodiode produces a difference frequency signal which is a sub-harmonic (divided-by-2) of the primary modulation frequency. This all optical circuit is simple, novel and low noise in character.
