Abstract
The optical device includes a waveguide positioned on a base and a modulator positioned on the base. The modulator includes a ridge that includes Si1-xGex where x is greater than or equal to 0.4 and less than or equal to 0.8. The modulator is configured to guide a light signal through the modulator such that the light signal contacts the Si1-xGex. A local heater is configured to heat the modulator.
