Latest Patents

Yamashita's latest patents include a grating lens and a focusing grating coupler. The grating lens features a design where the diffraction efficiency varies in the focusing direction of light on the lens surface. The focusing grating coupler also showcases a variable diffraction efficiency of a grating formed on an optical waveguide, which is situated on a substrate. Additionally, he has developed an optical element that consists of a substrate and a composite grating pattern. This pattern is made up of two different grating designs superimposed on the substrate. One of these patterns is a Fresnel lens pattern, which provides a light focusing function. The other is an equally separated linear grating pattern that allows for light diffraction. When combined, these patterns enable the optical element to focus light onto a point and create a cylindrical lens function.
