Abstract
An optical waveguide structure. In some embodiments, the optical waveguide structure includes a semiconductor waveguide having a waveguide ridge, and a heater. The waveguide ridge may have a varying dopant concentration across its cross-section. The heater may include a first contact and a second contact, and the waveguide structure may include a conductive path from the first contact to the second contact, the conductive path extending through a doped portion of the waveguide ridge.
