Abstract
The optical device includes a waveguide positioned on a base and a modulator positioned on the base. The modulator includes a ridge of an electro-absorption medium having a top side and a lateral side. The lateral side is between the top side and the base and the top side has a width. The waveguide is configured to guide a light signal through the modulator such that the light signal is guided through the ridge of electro-absorption medium. A heater is positioned over the lateral side of the electro-absorption medium without being positioned over the entire width of the ridge.
