Latest Patents

One of his latest patents is titled "Fast switchable and high diffraction efficiency grating ferroelectric liquid crystal cell." This invention presents a liquid crystal cell structure that includes two polarizers and a liquid crystal diffractive light modulating cell placed between them. The cell features two transparent substrates treated by photoalignment, along with a ferroelectric liquid crystal layer that is disposed between the substrates. This layer comprises ferroelectric liquid crystals and is designed to provide multiple alignment domains with a planar surface orientation. The adjacent domains are oriented at an angle with respect to each other, enhancing the cell's performance.

Another notable patent is related to "Multi-mode interferometer techniques." This patent describes technologies useful in an interferometer system. The system includes a first waveguide that propagates a first wave in a first mode. Additionally, a second waveguide is included, which responds to the first wave by propagating second and third waves in their respective modes. The second waveguide can reflect these waves off a reflection surface, producing multiple reflected waves that can be propagated in different modes.
