Title: Reiko Kojima: Innovator in Optical Fiber Technology
Introduction
Reiko Kojima is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of optical fiber technology. Her innovative work has led to the development of a unique patent that enhances the functionality of optical fibers.
Latest Patents
Kojima holds a patent for a "Slant short-period grating." This invention involves a slant short-period grating that is created by irradiating light onto an optical fiber. The core of the fiber is made from quartz glass, which is doped with a photosensitive dopant that alters the refractive index of the glass when exposed to light. The cladding of the fiber consists of one or more layers, with at least the layer adjacent to the core being a photosensitive layer. The grating portion is formed by changing the refractive index of both the photosensitive layer and the core at a predetermined grating period along the fiber's longitudinal direction. The design ensures that the core's diameter is set to 5 µm or more, and the relative photosensitivity ratio is optimized to achieve specific performance criteria. This innovation results in loss peaks in a narrow frequency band within the wavelength spectrum of transmitted light.
