Latest Patents

Onishi holds a patent for an "Optical functioning glass and apparatus using the same." This invention enables optical amplification at the 1.3-micrometer wavelength band, enhancing the efficiency of amplification. The optical functioning glass contains Nd³⁺ as an active material and uranium, both of which are doped in a multi-component function glass serving as a host glass. The inclusion of uranium allows for the absorption of light emission from Nd³⁺ in the 1.06-micrometer wavelength band, preventing a decrease in efficiency of induced emission in the 1.3-micrometer wavelength band. This innovation leads to the creation of a low-threshold, high-gain fiber amplifier and fiber laser when a fiber is formed using the optical functioning glass as a core.
