ABSTRACT:
A stress-optical phase modulator and modulation system, and method of use of the same is described. The stress-optical phase modulator comprises a source for providing optical beams, a photoelastic optical material, and a means for applying mechanical force to the optical material. The mechanical force so applied creates a uniform stress within the optical material and results in a change in its index of refraction. An optical beam passing through the stressed optical material undergoes a phase change and is recovered as a phase modulated optical beam. Components may be added to the stress-optical phase modulator to produce temperature-compensated and intensity-modulated optical beams.
