Latest Patents

Fujiyama's latest patents focus on ultra-thin polarization mode converters based on liquid crystal materials. One of his inventions includes a method and apparatus that features a first waveguide segment that differentially changes the amplitude of light relative to a first polarization orientation. This design incorporates a thickness of oriented liquid crystal or other birefringent material that delays one polarization component by one-half wavelength relative to another. Additionally, the apparatus includes a second waveguide segment that also differentially changes the amplitude of light based on the polarization orientation. Another aspect of his work involves a thin polarization converter that consists of a thin first substrate, which is substantially transparent to a wavelength of light, and a birefringent material deposited on one or more surfaces of the first substrate. This configuration allows the polarization converter to form a half-wavelength birefringent plate for the light. Furthermore, he has developed an apparatus that includes a first substrate surface, a second substrate surface, and a liquid crystal material positioned between them to create a polarization converter.
