Latest Patents
Atuhiko Niwa holds a patent for an optical fiber that features a slanted optical fiber grating, a band rejection optical filter, a gain equalizing optical filter for optical amplifiers, and an optical amplifier module. The invention focuses on the photosensitivity of the inner and outer cores of the optical fiber. The inner core, located at the center, exhibits low photosensitivity, while the outer core, situated close to the cladding, shows high photosensitivity. Additionally, the inner cladding near the core has high photosensitivity, whereas the outer cladding has low photosensitivity. This configuration allows for the creation of multiple slant optical fiber gratings with varying optical characteristics, enabling the formation of a gain equalizing optical filter. This innovation ensures that the optical filter maintains its filtering characteristics within a narrow bandwidth while enlarging the loss area.
