Abstract:
The embodiments herein describe a single-frequency laser source (e.g., a distributed feedback (DFB) laser or distributed Bragg reflector (DBR) laser) that includes a feedback grating or mirror that extends along a waveguide. The grating may be disposed over a portion of the waveguide in an optical gain region in the laser source. Instead of the waveguide or cavity being linear, the laser includes a U-turn region so that two ends of the waveguide terminate at the same facet. That facet is coated with an anti-reflective (AR) coating.

Claim (Index 16):
The optical system of  claim 11 , wherein the grating is disposed over a third portion of the waveguide extending through the intermediate region that is spaced apart from the second portion of the waveguide extending through the intermediate region, wherein the grating is continuous over the second and third portions of the waveguide.
