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 8):
The laser source of  claim 1 , further comprising:\n an optical combiner disposed in the facet, wherein the first and second ends terminate at the optical combiner, wherein an output of the optical combiner is configured to emit an optical signal to an external optical component.
