Title: Guomin Jiang: Innovator in Optical Technology
Introduction
Guomin Jiang is a prominent inventor based in Fremont, CA, known for his contributions to optical technology. With a total of 5 patents, he has made significant advancements in the field of wavelength selective switches and liquid crystal technology.
Latest Patents
One of his latest patents is titled "Tunable optical wedge for reducing crosstalk in wavelength selective switch." This invention involves a wavelength selective switch where an input port transmits an input beam that is dispersed into optical channels by a diffraction grating. The liquid-crystal-on-silicon (LCoS) switch assembly features a phase grating profile with addressable pixels that are liquid crystal-based. The tunable optical wedge adjacent to the LCoS switch assembly directs higher-order diffraction beams to minimize crosstalk between output ports. The wedge consists of a liquid crystal cell with spaced-apart resistive layers, allowing the liquid crystal material to produce a phase profile in response to applied bias voltages.
Another notable patent is "Reconfigurable port arrays for wavelength selectable switch." This invention features a reconfigurable polarization rotator made up of an array of microcells, each less than 10 μm in width. Each microcell can be independently controlled by separate electrical voltage inputs, allowing for the formation of a polarization rotator window that can be adjusted based on the configuration of the fiber array used.
