Nanoscale liquid crystal polymer Bragg polarization gratings
Report on a diffraction grating with wider angular bandwidth and significantly higher average first-order efficiency than the nearest prior art of metasurfaces, volume holographic gratings, and surface-relief gratings configured to achieve a steep deflection angle.
Bragg polarization gratings for wide angular bandwidth and high efficiency at steep deflection angles
Experimentally demonstrate nearly ideal liquid crystal (LC) polymer Bragg polarization gratings (PGs) operating at a visible wavelength of 450 nm and with a sub-wavelength period of 335nm.
Fabrication of ideal geometric-phase holograms with arbitrary wavefronts
General paper that discusses ideal goemetric phase holograms as an alternative method to controlling phase using polarization instead of path length difference. Two methods to create high-fidelity GPHs and eight representative examples of GPHs are discussed.
