Abstract:
1. An improvement in an electro-optic modulator, which is comprised of a first substrate, an optical transmission network on the first substrate, a plurality of separate segmented electrodes distributed in a cascade arrangement on the first substrate in the direction of optical transmission for modulating successive respective segments of the optical transmission network, a second substrate, and a plurality of separate modulating signal transmission lines disposed on the second substrate lateral to the optical transmission network on the first substrate for transmitting modulating signals to respective ones of the segmented electrodes to modulate an optical signal transmitted through the optical transmission network, the modulating transmission lines having respective input ends and individual lengths that are selected so that modulating signals applied to the input ends of the modulating transmission lines with a predetermined phase relationship reach their respective electrodes in synchronism with the propagation of an optical signal through the optical transmission network, the improvement comprising: a plurality of amplifiers disposed on the second substrate at the outputs of the modulating transmission lines, so that a maximum voltage is applied to each separate segmented electrode of the optical transmission network.
