Abstract
An electro-optic modulator device includes a modulation region, a reflecting region, a conductive line and an anti-reflecting region. The modulation region includes a doped region. The reflecting region is over the modulation region. The conductive line is connected to the doped region. The conductive line extends through the reflecting region. The anti-reflecting region is on an opposite surface of the modulation region from the reflecting region.
