Abstract
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.Keywords
