Latest Patents: Yu Zhang holds a patent for a "Chirped grating surface emitter with uniform power emission for beam-steering applications." This invention relates to the design of an optical phased array grating. The optical phased array grating includes an optical waveguide made of a first material with a uniform lateral width, which confines the optical waveguide as its core. Additionally, it features an overlay layer with a sequence of overlays made from a second material, which are spaced across the top surface of the optical waveguide. These overlays have continuously varying longitudinal duty cycles and lateral widths, with the second material possessing a lower optical index than the first material. The design is completed with a cladding layer made of a third material deposited over the overlay layer and the optical waveguide.
