Latest Patents

One of his latest patents is a fabrication technique for a wire grid polarizer. This innovative method avoids the need to etch through a multilayer stack of materials to form the grid structure. Instead, initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then employed to complete the fabrication by coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process covers the metal coating with a dielectric cladding material. This technique ensures that the top portions of the grid are suitably covered, creating the desired multilayer wire configuration.

Another significant patent is a system and method for generating a two-dimensional optical or laser beam, line, or pattern. This system includes a diffractive optical element (DOE) that modifies the intensity distribution of an input optical or laser beam. A focal lens receives the modified beam and focuses it, while bifocal relay optics magnify and adjust the focused beam. Finally, imaging optics converge and output the adjusted beam as an output optical or laser beam.
