Ultracompact, broadband slot waveguide polarization splitter
In this letter, we demonstrate an ultracompact polarization splitter design leveraging the giant birefringence of silicon-on-insulator slot waveguides. The fabricated splitter device has a coupling length of only 13.6 μ m , and shows average polarization extinction ratios of 21 dB and 17 dB for th...
