Title: Hiroshi Kato: Innovator in Optical Waveguide Technology
Introduction
Hiroshi Kato is a prominent inventor based in Vancouver, Canada. He has made significant contributions to the field of optical waveguide technology, holding two patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
Kato's latest patents include a passive method and apparatus for inducing mode conversion. This invention involves a waveguide designed for use in polarization mode converters and polarization modulators. It utilizes extrinsic strain to pre-rotate the principal axes and control birefringence. The method focuses on orienting the principal propagation axes in an optical waveguide by pre-stressing it with extrinsic stress, thereby achieving a substantially ideal orientation. The waveguide is stressed using an extrinsic strain inducer that applies shear force to induce anisometry in the waveguide structure.
Another notable patent is the enhanced performance mode converter. This optical mode converter features a slow wave electrode structure and incorporates Schottky barriers to prevent the accumulation of free carriers in the optical waveguide region. The Schottky barriers also suppress higher-order modes in the waveguide. Low refractive index insulators are employed to ensure efficient device operation without compromising the impedance or microwave index of the optical mode converter. Additionally, two-photon absorption processes are eliminated by using a waveguide semiconductor material with a bandgap at least twice the photon energy of the light beam propagating through the converter.
