Optical waveguide device including an electrical capacitive configuration

摘要

An optical device includes a waveguiding configuration and an electrical capacitive configuration. The capacitive configuration includes glass electrode region(s) and glass dielectric region(s) with electrical leads, e.g., metallic conductors, for applying electrical control signals to the electrode region(s). The preferred metals for the conductors are Ni, Ti and Au. The waveguiding structure is configured so that the fields associated with optical signals propagating therein interact with dielectric region(s). During the use of the device control signals are applied to the dielectric region(s) by the electrical leads. The control signals have the effect that temporary electric fields are applied to the dielectric region(s). The fields change the optical properties of the dielectric region(s) and this affects the propagation of the optical signals. The device can either be produced in planar or fibre configurations.
