Title: Kohroh Kobayashi: Innovator in Optical Technologies
Introduction
Kohroh Kobayashi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technologies, holding a total of 11 patents. His work focuses on enhancing the efficiency and functionality of optical devices.
Latest Patents
Kobayashi's latest patents include a connection structure of two-dimensional array optical elements and optical circuits. This innovation involves arranging optical elements, such as light sources or photodetectors, in a two-dimensional array. The design defines the positional relationship between the optical elements and optical waveguides, allowing for increased parallelism. Micromirrors are integrated into the optical waveguides to bend light beams by 90 degrees, facilitating efficient optical coupling. This structure is compact, highly efficient, and offers high parallelism.
Another notable patent is the bistable optical device, which features a semiconductor laser with a diffraction grating. This grating diffracts light parallel to itself for laser resonance while also diffracting a higher-order Bragg beam perpendicular to the grating. An optical detector captures this higher-order beam and generates an electrical signal that serves as a partial exciting current for the semiconductor laser. This design allows both optical ports of the laser to be utilized for additional purposes.
