We successfully fabricated a high-performance half-wave plate for the 405 nm wavelength based on monolithic integration of two nanograting layers. Each of the nanograting layers functions as a quarter-wave plate. Both of the nanograting layers were fully filled and planarized to achieve the monolithic integration. UV-nanoimprint lithography, along with(More)
High-performance true zero-order optical retarders were realized based on all-dielectric immersion nanogratings. All-dielectric nanolaminate materials, deposited by atomic layer deposition, were utilized to fill the trenches of the nanogratings to form immersion nanogratings. The refractive index of the nanolaminate material can be dialed and controlled(More)
