Abstract
A method of forming an optical device includes forming a waveguide mask on a device precursor. The device precursor includes a waveguide positioned on a base. The method also includes forming a facet mask on the device precursor such that at least a portion of the waveguide mask is between the facet mask and the base. The method also includes removing a portion of the base while the facet mask protects a facet of the waveguide.
