Quartz Polarization Grating PZGSF-200-355

LBTek Quartz Polarization Gratings are fabricated on UVFS substrates, featuring internally inscribed birefringent microstructures. The devices come as 1-inch single-substrate bare dies without housings.

Within the substrate, the fast axis orientation of the birefringent microstructure varies periodically and continuously along the x-direction, while maintaining uniform half-wave retardation across the entire device plane, making it a single-wavelength device.

These gratings introduce polarization modulation functionality compared to traditional gratings. Their planar structure, free of physical protrusions or depressions, facilitates integration. The substrate material choice ensures high damage threshold in the ultraviolet band.
