ABSTRACT:
An interferometric modulator uses a beamsplitter to produce deflected and transmitted light beams onto mirrored surfaces of a piezoelectric crystal pair, one piezoelectric crystal being driven by a modulating voltage signal, whereupon the light beams are reflected back to the beamsplitter to produce a modulated optical output signal, with the modulator being especially adaptable for use as an digital photonic clock, as a pulse width/amplitude modulator, and as a bistable optical memory cell.
