Integrated laser and coupled waveguide |
摘要 |
A grating (461) coupling the output of a semiconductor laser (410) in a semiconductor waveguide to a dielectric waveguide (451) having a core (458) which may be efficiently butt-coupled to the core of an optical fiber (470); the laser and semiconductor waveguide, coupling grating, and dielectric waveguide are integrated on a single substrate. Further, multiple lasers (410, 420, 430, 440) with differing lasing frequencies may be integrated and their outputs grating coupled into a single dielectric waveguide (450) for wavelength division multiplexing.
