Abstract (in Japanese) (See Japanese page) 
(in English) We attempted to inscribe refractive index modulated gratings in tellurite fibers to suppress the power of control light in an all optical switching application. A long period grating was inscribed in a tellurite fiber using picosecond pulsed Nd:YAG laser irradiation, where -12.6dB of attenuation peak was obtained in transmission spectrum. A tellurite fiber Bragg grating was fabricated using a two-beam interferometer with fundamental CW argon ion laser and an auxiliary heating with electric heater, where -1.67dB of attenuation peak was obtained in transmission spectrum. From the obtained transmission spectra, we estimated the refractive index changes as 0.125 for picosecond pulsed Nd:YAG laser irradiation and as $8 \times 10^{-5}$ for CW argon ion laser irradiation and auxiliary heating.
