    Abstract: An electro-optic device includes a semiconducting layer in which is formed a waveguide, a modulator formed across the waveguide comprising a p-doped region to one side and an n-doped region to the other side of the waveguide, wherein at least one of the doped regions extends from the base of a recess formed in the semiconducting layer. In this way, the doped regions can extend further into the semiconducting layer and further hinder escape of charge carriers without the need to increase the diffusion distance of the dopant and incur an additional thermal burden on the device. In an SOI device, the doped region can extend to the insulating layer. Ideally, both the p and n-doped regions extend from the base of a recess, but this may be unnecessary in some designs. Insulating layers can be used to ensure that dopant extends from the base of the recess only, giving a more clearly defined doped region. The (or each) recess can have non-vertical sides, such as are formed by v-groove etches, A combination of a vertical sidewall at the base of the recess and a non-vertical sidewall at the opening could be used.

    Abstract: A light modulation device comprises a substrate (1), a substrate layer (2), an optical waveguide layer (3) and buffer layers (4), in that order, formed of either all n-type or all p-type compound semiconductor crystal. In orderto capture the light in the optical waveguide layer, the composition ratio of the compound semiconductor is so determined that the refractive index is at least approximately 0.1% higher in the optical waveguide layers than in the substrate layer and in the buffer layers. Furthermore, the carrier density is low in the optical waveguide layer and in the buffer layers, so that the applied voltage is effectively applied mainly to the optical waveguide layer. Due to the construction of the light modulation device, strict control of the etching process is not required, the device has a low absorption loss of light, and it can be made as a monolithic optical integrated circuit.
