GRATING COUPLERS WITH DEEP-GROOVE NON-UNIFORM GRATINGS |
摘要 |
Grating couplers that enable efficient coupling between waveguides and optical fibers are disclosed. In one aspect, a grating coupler includes a transition region that includes a wide edge and tapers away from the edge toward a waveguide disposed on a substrate. The coupler also includes a sub-wavelength grating disposed on the substrate adjacent to the edge. The grating is composed of a series of non-uniformly distributed, approximately parallel lines and separated by grooves with a depth to output light from the grating with TM polarization. |
