ABSTRACT:
An improved high-speed external optical modulator, modulated by RF waves, which velocity matches the RF waves with the optical waves is disclosed. The apparatus includes a lithium niobate substrate on which is formed an optical waveguide, electrically floating electrodes, a low dielectric buffer layer and electrodes carrying the modulating RF energy. At least one floating electrode may comprise a series of spaced electrode segments for enhanced performance at high frequencies.
