摘要： A base device has a first waveguide positioned on a first base. The waveguide is at least partially defined by a ridge extending away from the first base. An auxiliary optical device has a second waveguide positioned on a second base. The second optical device is immobilized on the base device such that the second waveguide is between the first base of the first optical device and the second base of the auxiliary device. The first waveguide is optically aligned with the second waveguide such that the first waveguide and second waveguides can exchange optical signals.

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.
