ABSTRACT:
The concept of using only a component of an applied electric field to control the electrooptic response in each element of a multi-crystal electrooptic modulator comprising a matched grouping of birefringent electrooptic elements is disclosed. The foregoing concept permits the orientation of the polarization eigenvectors of the grouped elements to compensate for the effects of the static birefringence of the material comprising the elements while retaining the use of parallel applied electric fields and eliminating the need for an interposed optical rotator or waveplate.
