Abstract

High-speed optical intensity modulation is reported for the first time using single-mode electro-optic interferometric waveguide modulators formed from Ti-diffused waveguides in LiNbO3. For cw 0.633-μm optical inputs, modulation at rates up to 1.4 GHz has been achieved by driving the interferometer through multiple-π phase shifts. Envelope modulation of a 275-MHz optical pulse train from a cw mode-locked frequency-doubled Nd:YAG laser with a 68.9-MHz drive signal has also been demonstrated.
