TL;DR: In this article, a novel method of adjusting the dispersion of fiber Bragg grating using the non-uniform stress effect is proposed by loading the axial stress on the fiber grating coated with nonuniform copper thin-film.

TL;DR: In this paper, a new kind of optical fiber grating pressure sensor combined with computer monitor is designed for train real-time tracing, the parameters of train can be given, such as position, length, velocity, acceleration, disjoint and so on.

TL;DR: In this article, the effects of the air hole size on PFBG's transmission properties such as effective index, Bragg reflective wavelength, normalized bandwidth and center======wavelength shift are investigated.

TL;DR: In this paper, the authors proposed a hexagon boron nitride (h-BN)-graphene-silica grating-based structure and demonstrated that the structure can be realized both within the upper reststrahlen (RS) band and outside the RS band by tuning the chemical potential of graphene and changing the geometry parameters of the proposed structure.

TL;DR: In this paper, the authors studied the effect of polarization mode dispersion (PMD) on Gauss pulse transmission over ultra-high PMD fiber and showed that PMD is a distortion arising from unwanted birefringence in optical fiber.
