Examples described herein relate to an optical coupler. The optical coupler may include a first optical waveguide base layer, a second optical waveguide base layer, an insulating layer disposed over at least a portion of both the first optical waveguide base layer and the second optical waveguide base layer, and a semiconductor material layer disposed over the insulating layer. Overlapping portions of the first optical waveguide base layer, the insulating layer, and the semiconductor material layer form a first optical waveguide, and overlapping portions of the second optical waveguide base layer, the insulating layer, and the semiconductor material layer form a second optical waveguide. Moreover, the optical coupler may include a plurality of metal contacts to receive one or more first biasing voltages to operate one of the first optical waveguide base layer and the second optical waveguide base layer in an accumulation mode.
