ABSTRACT:
A velocity match between a traveling optical wave and an interacting traveling electrical wave having a different velocity of propagation is simulated by shaping the electrical signal path so that interaction between the two waves occurs along selected regions of the electrical signal wavepath. In particular, the electrical wavepath bends away from the optical wavepath at uniformly spaced intervals to produce regions of no interaction along the electrical wavepath. This technique is employed to modulate optical waves via the electrooptic effect.
