Mode Characteristics and Sensing Performance of Fiber Gratings
Journal of Harbin University of Science and Technology, 2022 Fiber gratings are special optical fibers with a periodic refractive index distribution when the refractive index of the fiber core is modulated. Both the angle and period of the gratings have an influence on the sensing properties of the fiber gratings.

Fiber Bragg Grating Based Thermometry [PDF]
NCSLI Measure, 2015 In recent years there has been considerable interest in developing photonic temperature sensors such as the Fiber Bragg gratings (FBG) as an alternative to resistance thermometry. In this study we examine the thermal response of FBGs over the temperature range of 233 K to 393 K.

Phase encoding and decoding of short pulses at 10Gb/s using superstructured fiber Bragg gratings [PDF]
, 2001 A 7-chip, 160-Gchip/s phase-shift keyed code is assigned to short pulses after reflection from a superstructured fiber Bragg grating. The code is then recognized by a second grating, which is nominally identical to the encoder grating.

Bragg gratings and BIO-Bragg-gratings in tapered optical fibers
EPJ Web of Conferences, 2022 Tapered optical fibres are well-established devices for different applications, in order to exploit nonlinear effects, manage dispersion, excite azimuthal resonances in microresonators (so-called Whispering Gallery Modes). Also, the micro- or nanofibres guide optical-fields with large evanescent fields. In this talk, we will focus on the combination of

Direct characterization of the spatial effective refractive index profile in Bragg gratings [PDF]
, 2005 We propose a pulse response method to directly characterize the phase of the spatial index modulation, including the dc refractive index distribution (distributed phase shift), discrete phase, and chirp of fiber Bragg gratings (FBGs).
