Abstract
An optical modulator device includes a body portion operative to propagate an optical mode along a longitudinal axis of the body portion, the body portion comprising a first layer disposed on a second layer, wherein the first layer includes a first p-type doped region adjacent to a first n-type doped region along the longitudinal axis of the body portion, and the second layer includes a second n-type doped region disposed on the first p-type doped region and a second p-type doped region adjacent to the second n-type doped region along the longitudinal axis of the body portion, the second p-type doped region disposed on the first n-type doped region.
