Bragg polarization gratings for wide angular bandwidth and high efficiency at steep deflection angles
Abstract Optical films and surfaces using geometric phase are increasingly demonstrating unique and sometimes enhanced performance compared to traditional elements employing propagation phase. Here, we report on a diffraction grating with wider angular bandwidth and significantly higher average firs...
