A high-speed Bragg-type electro-optic modulator with modified interdigital electrodes has been constructed using a Li out-diffused waveguide layer in LiNbO3. The thickness of the layer is about 7 μm and only two modes, TE0 and TE1, are supported. For the TE0 mode, a maximum modulation index of about 70% is obtained up to 900 MHz with an applied voltage of 18 V.
