In-Fiber Bragg-Grating Sensors
Optical Fiber Sensors, 1988In 1978. K. O. Hill and colleagues1 reported the formation of refractive index gratings in germanosilicate core, silica clad fibers by injection of 488 and 514.5 nm argon-ion laser radiation into one end of the core. A few years later, Lam and Garside2 showed the grating strength increased as the square of the power flux, suggesting a two-photon ...

Fiber Bragg gratings for telecommunications
Proceedings of 2001 3rd International Conference on Transparent Optical Networks (IEEE Cat. No.01EX488), 2002Fiber Bragg gratings (FBGs) are nowadays widely used in various fields, including telecommunications. Since its emergence, this component has found many applications due to its properties, versatility and variety of controllable parameters that can shape in various manners its spectral properties.

In many network and sensor applications, small amounts of light need to be coupled out at many points from a transmission bus fiber. In-line devices with some wavelength selectivity are particularly desirable, especially if light radiated from the fiber can be efficiently coupled into another fiber.

Fiber Bragg grating technology
Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society, 2002Bragg gratings in fiber and planar waveguides are now coming into practical use for telecommunications, data communications, and signal processing applications. New high power fiber lasers are also using fiber gratings. Various devices for these applications require different types of Bragg gratings.

Radiation dosimetry with fiber Bragg gratings
SPIE Proceedings, 2014The measurement and monitoring of radiation dose delivered in patient tissues is a critical aspect in radiation therapy. Various dosimeters have proven effective in measuring radiations at low doses. However, there is a growing demand for new dosimeters based on small, non-invasive and high resolution devices.

Regeneration of tilted fiber Bragg gratings
SPIE Proceedings, 2014The regeneration of Tilted Fiber Bragg Gratings photowritten in a singlemode SMF-28e fiber is investigated. Three tilted FBGs, with respectively 0°, 4° and 8° external tilt angles are annealed according to a conventional high temperature regeneration protocol.

According to the optical structure and sensing principle, fiber gratings are divided into phase shift grating, chirped grating, blazed grating, long period grating, and Bragg grating. Based on the basic principle and theoretical analysis of fiber Bragg grating, this chapter systematically introduces and analyzes the sensing principle, structure design ...

Tilted fiber Bragg grating sensors
Laser & Photonics Reviews, 2012AbstractOptical fiber gratings have developed into a mature technology with a wide range of applications in various areas, including physical sensing for temperature, strain, acoustic waves and pressure. All of these applications rely on the perturbation of the period or refractive index of a grating inscribed in the fiber core as a transducing ...

An optical fiber polarizer is constructed with a fiber Bragg grating (FBG) based on birefringence effects induced by a transverse force applied to a section of the grating. In this work we present the principle of operation and experimental results of this device.

Polymer micro-fiber Bragg grating
Optics Letters, 2013Polymer micro-fibers with inscribed Bragg gratings are reported in this Letter. Starting with a single-mode polymer optical fiber and implementing a two-stage tapering process, a 16 μm diameter micro-fiber is fabricated and a Bragg grating is inscribed in it that exhibits a peak reflected wavelength circa 1530 nm.
