Generation of optical signals carrying OAM based on vortex fiber-optic periodic structures
Физика волновых процессов и радиотехнические системы, 2020 In this article, author considers the process of generation of fiber modes carrying orbital angular momentum (vortex modes) using chiral fiber Bragg gratings; in this context, the formation of vortex modes is carried out by converting thefundamental mode

Bound States in the Continuum in Fiber Bragg Gratings [PDF]
ACS Photonics, 2017 Optical fibers typically confine light through total internal reflection or through photonic bandgaps. Here we show that light can be perfectly guided in optical fibers through a different mechanism based on bound states in the continuum (BICs).

A Fiber Bragg Grating-Based Anemometer [PDF]
Sensors, 2018 A novel fiber anemometer based on two pairs of fiber gratings is experimentally demonstrated and can simultaneously detect wind speed and wind direction. One pair of gratings, which are separated by 90° in space, is fixed on a small stainless steel pipe driven by a rotating disc for measuring the wind-direction angle.

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.
