Abstract

A resonant-cavity electro-optic phase modulator is designed, implemented, and experimentally verified to operate at a data rate of 100 Mbits/s. The cavity is made up of a highly reflective backmirror and the partially reflective end of an electro-optic crystal. A voltage signal applied to the electro-optic crystal perturbs the effective optical path length inside the cavity and hence its resonance frequency. Because the phase of the reflected optical signal from the cavity is highly dispersive when the cavity is tuned near resonance, a cw incident signal will experience a large phase shift as the cavity is electro-optically tuned on and off resonance. This phase-dispersion effect can be used in the construction of an optical phase modulator capable of modulating the signal at data rate in excess of 100 Mbits/s. The performance of the modulator was measured by first heterodyne detecting the signal to an intermediate frequency and then measuring the spectral characteristics with a radio frequency spectrum analyzer. The measured phase shift is shown to be in good agreement with theoretical predictions.
