Latest Patents

Kristian Buchwald holds a patent for a "Polarization independent grating." This grating is designed to achieve high diffraction efficiency into the minus first diffracted order in transmission, accommodating both TE and TM polarizations. The design allows for the incident angle to be selected so that the minus first diffracted order in reflection can be retroreflected back to the incident beam. The grating can be constructed from various materials and layers, with the thicknesses of these layers determined through optimization or simulation processes. Notably, the grating may consist of four or more layers formed from three or more materials, and it can feature a longitudinal refractive index profile with at least two local extrema.
