Polarization Splitter/Combiner Based On A One-Dimensional Grating Coupler |
摘要 |
A grating coupler comprising a semiconductor substrate, a one-dimensional (1D) grating element coupled to the semiconductor substrate, wherein the 1D grating element is adapted to simultaneously couple a first polarization component of an incident optical beam with a transverse electric (TE) waveguide mode in a first propagation direction and a second polarization component of the incident optical beam with a transverse magnetic (TM) waveguide mode in a second propagation direction, and wherein the first propagation direction is opposite of the second propagation direction. |
