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. The portion of the base that is removed can be removed such that a recess is defined in the base and/or a shelf is defined on the device precursor. A light source such as an optical fiber or laser can be received in the recess and/or positioned over the shelf such that the light source is optically aligned with the facet of the waveguide.
