Electro-Optical Resonant Phase Modulator
Abstract
Electro-optical phase modulator includes electro-optical crystal in resonant cavity suitable for use in transmitting digital data on laser beam at data rate of 10 MHz. Switching voltages applied to crystal, thereby switching cavity onto and off resonance, and large phase dispersion occurring near resonance provides output phase modulation. Driving voltages smaller than those of nonresonant modulators. Laser-damage thresholds of apparatus, incorporating bulk optics, inherently greater than modulators based on integrated optics.
