Optical device having reduced optical leakage

摘要

An optical device includes a ridge on a base. The ridge includes an active medium. An active component on the base is a light sensor and/or a light modulator. The active component is configured to guide a light signal through the active medium included in the ridge. Electrical current carriers contact the lateral sides of the ridge on opposing sides of the ridge. Each of the electrical current carriers includes a carrier material that is doped so as to increase the electrical conductivity of the carrier material. The carrier material is different from the active medium.
