The LBTek Checkerboard Grating (CG) is fabricated on an N-BK7 glass substrate using birefringent liquid crystal polymer (LCP) material, featuring a sandwich structure of front and rear glass substrates plus intermediate LCP functional film layer without mechanical housing, with a 1.5 mm single-sided chamfer.

The device utilizes liquid crystal molecules arranged in a checkerboard pattern with uniform orientation angles within each pixel cell and a phase difference between adjacent cells. Compared to three-piece cascaded structures, a single checkerboard grating accomplishes the same 2x2 uniform beam splitting function with easier integration.
