Latest Patents
Among his latest patents is a "Polarization analyzer using a plurality of Faraday rotators." This invention utilizes Faraday rotators, each equipped with a Faraday element that rotates light, along with a magnetic field generator. The design includes a wavelength plate that retards the light, allowing a polarizer to transmit light with a predetermined plane of polarization. An optical receiver captures the transmitted light and generates a corresponding light receiving signal. A signal generator controls the polarization of the light to be measured, while a signal processor determines the Stokes parameters indicating the polarization state.
Another notable patent is the "Multiwavelength light source device employing annular optical delay circuit." This apparatus features a tunable light source, optical intensity modulator, optical coupler, annular optical delay circuit, and optical gate device. The tunable light source outputs multiple wavelengths of light, which are then modulated and processed to ensure that all signal light is included for each wavelength.
