New Beam Splitting Polarizer Cube

Summary Traditional polarizing beamsplitter cubes rely on MacNeille coatings, but a new approach using wire grid structures on the cube hypotenuse offers enhanced polarization purity across a broader range of wavelengths and angles. Modern lithography techniques now enable the creation of ultrafine wire grids, ensuring high-performance polarization control at both visible and near-infrared wavelengths. This […]
