Abstract

An optical modulator with CPW electrode on Ti:LiNbO$_3$ optical waveguide was fabricated and chterized. The electrical-optical bandwidth measurement showed an optical response of -3dB at 10 GHz and S11 less than -l0dB unto 20GHz. The typical specifications are . 5.6V of driving voltage, 4.2dB of Insertion loss and 30dB of on/off extinction.
