Abstract
A grating (,) assisted coupling of a semiconductor waveguide to a dielectric waveguide (,) is provided with one or more reflective stacks (,) to enhance the coupling efficiency. The glass or dielectric core (,) may be efficiently butt-coupled to the core of an optical fiber (,). A laser and semiconductor waveguide, reflective stacks coupling grating, and dielectric waveguide are integrated on a single substrate. Further, multiple lasers (,) with differing lasing frequencies may be integrated and their outputs grating coupled into a single dielectric waveguide (,) for wavelength division multiplexing.
