BIREFRINGENCE IN AMORPHOUS SOLIDS WITH APPLICATION TO SOLID LIGHT MODULATORS

Abstract

The theory of birefringence in a transparent, amorphous solid is developed from fundamental principles in order to obtain a design formulation for spatial light modulators that will operate at 100 MHz center frequency with at least 50 percent bandwidth. Both longitudinal and shear wave elasto-optical interactions are treated. Relations for the phase modulation index and the diffracted light intensity and polarization, as functions of the modulator parameters, are presented for the case of normal light incidence. The effect of internal refraction on the first-order peak intensity is then quantitatively examined. From this consideration, a criterion for obtaining maximum optical performance in the modulator is derived. An analysis of the quartz transducers used to generate the elastic waves in the modulators is presented as an integral part of the design formulation. The effect of lead and indium bonds on transducer response is treated in detail.
