TL;DR: In this article, a method to compensate the temperature sensitivity using a boron codoped germanosilicate core fiber as a host fiber was proposed, which was shown to have a high temperature sensitivity, typically 0.05 nm/spl deg/C at room temperature.

TL;DR: In this article, a PANDA fiber grating was used for simultaneous measurement of temperature and strain using a probe size as small as few millimeters, which is promising as a local sensing device for various applications.

TL;DR: In this paper, an optical fiber filter provided with a portion which selectively reflects or transmits light of a specific wavelength, this portion comprised of a multimode optical fiber in which the refractive index of the core changes periodically along the longitudinal direction thereof.

TL;DR: An optical waveguide grating with radiative mode-coupling properties, with exceptional stability and reliability as an optical component, wherein the central wavelength of the rejection band has a low temperature dependence, due to the use of silica glass doped with germanium and boron for the core.

TL;DR: In this paper, a new technique for fabricating an LPFG by local heating of a pure-silica core fiber to release residual stress of a core without fiber deformation is proposed.
