Broadband. High-Extinction-Ratio, and Low-Excess-Loss Polarizer Based on Horizontal Slot Silicon Bragg Grating

A broadband (264 nm), high extinction ratio (>30 dB), low excess loss (<0.3 dB), and compact (10.64 µm) TM-passITE-block polarizer is proposed and investigated based on the horizontal slot silicon Bragg grating.
