Abstract
The specification describes photonic integrated circuit structures, and methods for making structures in which the active and passive waveguides are coplanar, and further in which all the layers of both the active and passive device regions are essentially coplanar, resulting in a planar surface and design flexibility for contact pad and metallization placement. The fabrication strategy eliminates the deep etch used in conventional processing to form laser devices, and thereby eliminates the step between the laser mesa and the passive waveguide sections.
