US Patent 10241354 Electro-optic modulator with a periodic junction arrangement

Techniques regard electro-optic modulators are provided. For example, one or embodiments described herein can regard an apparatus that can comprise a first lateral region, a second lateral region, and a central region located on a semiconductor substrate. The first lateral region can be adjacent to a first side of the central region and can have a first conductivity type. The second lateral region can be adjacent to a second side of the central region and can have a second conductivity type. Also, the first side can be opposite to the second side. Further, the central region can comprise a diode junction adjacent to an intrinsic region. The intrinsic region can separate the first lateral region and the second lateral region.
