ABSTRACT:
A modulating optical element having ports wherein either port can output or receive light signals. An electrooptic effect is applied to the optical element to allow the light signals to pass or not pass through the optical element. Due to the electrooptic effect in preventing signals from passing through the optic element, light signals radiate out of the optical element and are absorbed by the substrate of the optical element assembly. Rather than being lost, the energy from the light signal is converted to current which may be used for other purposes in the modulator system, such as bias stabilization.
