Title: Morio Watanabe: Innovator in Optical Fiber Technology
Introduction
Morio Watanabe is a distinguished inventor based in Yokohama, Japan. He has made significant contributions to the field of optical fiber technology, holding a total of 4 patents. His work focuses on developing optical fibers that enhance performance in telecommunications.
Latest Patents
Watanabe's latest patents include innovations related to optical fibers designed to have a large positive dispersion in the wavelength band of 1.55 µm. This design aims to compensate for the negative dispersion inherent in Non-Zero Dispersion Shifted Fiber (NZ-DSF) within the same wavelength band. The optical fiber features a depressed cladding structure, which consists of a core region, an inner cladding with a lower refractive index, and an outer cladding with a higher refractive index. The relative refractive index difference of the core region with respect to the outer cladding is maintained between 0.30% and 0.50%. Additionally, the inner cladding's relative refractive index difference with respect to the outer cladding ranges from -0.50% to -0.02%. This innovative optical fiber achieves a dispersion greater than 18 ps/nm/km at a wavelength of 1.55 µm, along with an effective area of at least 70 µm² at the same wavelength.
