Latest Patents

One of Hiroaki Abe's latest patents is for an optically active single crystal and its fabrication process. This invention discloses a unique optically active single crystal that contains both levo-rotatory and dextro-rotatory portions. It is designed to be even in optical rotatory power and physical constants, such as electrooptic constant and Faraday constant. The fabrication process involves growing a single crystal using the crystal pulling method, utilizing a seed crystal made from both levo-rotatory and dextro-rotatory single crystals. This method allows for the efficient and rapid production of the optically active single crystal.

Another notable patent is for a spatial light modulating element that employs a uniaxial single crystal of oxide. This element includes an electrooptic and photoconductive single crystal plate, along with a light-transmitting insulating layer on at least one of its surfaces. The insulating layer is formed from a uniaxial single oxide crystal, which is oriented to avoid birefringence and electrooptic effects in the direction of the electric field. The materials used for the insulating layer may include LiNbO3, LiTaO3, or TiO2 (rutile) single crystal plates.
