ABSTRACT:
Because the refractive index of materials varies as a function of frequency, velocity matching of the electrical modulating signal and the optical signal in an optical velocity matched gate requires a special design of the electrical circuit. This requirement is avoided in a velocity mismatched gate simply by shaping the electrical signal wavepath so that interaction of the standing electrical wave with the optical wavepath occurs only along selected regions of the electrical signal wavepath. The net effect is to produce the equivalent of a velocity match.
