Abstract
A method of forming an optical device includes using a photomask to form a first mask on a device precursor. The method also includes using the photomask to form a second mask on the device precursor. The second mask is formed after the first mask. In some instances, the optical device includes a waveguide positioned on a base. The waveguide is configured to guide a light signal through a ridge. A heater is positioned on the ridge such that the ridge is between the heater and the base.
