Abstract (in Japanese) (See Japanese page) 
(in English) Strain can be detected at high speed using a fiber Bragg gratings (FBG) by measuring the optical power fluctuations at the central wavelength of the slope of the reflected spectrum, instead of measuring the Bragg wavelength shift directly. In this high-speed strain detection, a narrow-linewidth laser with a wavelength at the center of the slope is generally used, but the accurate pre-design of the inscription pitch of the FBG leads to its high fabrication cost. In this work, using an FBG inscribed in a perfluorinated graded-index plastic optical fiber (multimode fiber), we show that Bragg wavelengths appear in arbitrary wavelength ranges of the reflection spectrum. This unique behavior can be obtained by suppressing the excitation of the fundamental propagation mode and promoting the excitation of the higher modes. We experimentally show that, by exploiting this feature, high-speed strain measurement can be performed at almost arbitrary wavelengths. We also investigate the wavelength dependence of the vibration sensing performance (sensitivity, etc).
