We report on an ultra-compact. low loss and broadband TM-pass polarizer. which is constructed by two interleaved subwavelength-gratings (SWGs) waveguides inserted in the center of the strip waveguide on a silicon-on-insulator (SOI) platform. The device structure is optimally engineered to support Bloch mode for fundamental TM polarization only. https://www.roneverhart.com/Electric-Swingarm-XL/
