Latest Patents

One of his latest patents is a method of making micro-optical components on polydiacetylene optical. This method involves exposing polydiacetylene to an e-beam or similar exposing means, which causes a change in the index of refraction of the material. The e-beam exposure technique allows for direct control without the need for physical or chemical preparation of the polydiacetylene. The depth of penetration of the e-beam can be adjusted by controlling the scanning rate and intensity, resulting in optical gratings that possess nonlinear optical properties suitable for various applications.

Another notable patent is for an optical device with surface plasmons. This device functions as an optical switch or bistable device and consists of a semiconductor base material that forms a non-linear dielectric layer alongside a metal layer. The interface between these layers includes a submicron grating. The device is optically excited by a light source of specific intensity, allowing for the dispersion relation of surface plasmons to be altered by varying the input laser intensity, thus enabling bistable or hysteresis effect switching.
