Wavelength tunable TFBG based microwave sensor using surface plasmon resonance
Egyptian Journal of Remote Sensing and Space Sciences, 2016 A noble idea is used to propose a wavelength tunable tilted Fiber Bragg Gratings based microwave sensor using surface plasmon resonance. The Bragg wavelength shifts linearly about 6 pm/°C, due to the temperature change.

Bioresorbable optical fiber Bragg gratings [PDF]
Optics Letters, 2018 We demonstrate, for the first time, an inscription and wet dissolution study of Bragg gratings in a bioresorbable calcium-phosphate glass optical fiber. Bragg gratings, with average refractive index changes of 5.8×10-4, were inscribed using 193 nm excimer laser radiation.

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.

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

Writing Bragg Gratings in Multicore Fibers [PDF]
Journal of Visualized Experiments, 2016 Fiber Bragg gratings in multicore fibers can be used as compact and robust filters in astronomical and other research and commercial applications. Strong suppression at a single wavelength requires that all cores have matching transmission profiles. These gratings cannot be inscribed using the same method as for single-core fibers because the curved ...
