Differential birefringence in Bragg gratings in multicore fiber under transverse stress.

چکیده
We present experimental measurements of the peak splitting of the reflection spectra of fiber Bragg gratings as a result of birefringence induced by transverse loading of a multicore fiber. Measurements show that the splitting is a function of the applied load and the direction of the load relative to the azimuth of the fiber. A model for calculating the stress in the fiber that is due to an applied load is in good agreement with our experimental observations.

UV-induced modification of stress distribution in optical fibers and its contribution to Bragg grating birefringence.
This paper discusses the importance of stress-induced contributions to the photo-induced birefringence observed in fiber Bragg gratings. Optical tomography measurements are performed in exposed and unexposed fibers to extract the stress profiles induced by UV-writing of fiber Bragg gratings for various exposure levels. A photoelastic analysis and a high-order isoparametric finite elements metho...

With the fluctuation of the environmental factors, such as temperature, wind, and atmospheric pressure, the birefringence of a fiber changes along the fiber link and the effects of polarization mode dispersion (PMD) are random and time-varying, which makes it necessary to design a tunable and adaptive Fiber communication; Optical fiber; Fiber Bragg grating; Differential group delay; Dispersion ...
متن کاملNonlinear Fiber Bragg Gratings
In this paper we review some of the dominant topics in fiber Bragg gratings (FBGs). The combination of theory and simulations shows that these structures can use in filters, nonlinear fiber optical applications, soliton propagations etc. We discussed the theory of FBGs, grating solitons, Bragg soliton generation in intrinsic media and birefringence effects in FBGs together with some numerical s...
متن کاملPoint-by-point inscription of first-order fiber Bragg grating for C-band applications.
The influence of the fiber geometry on the point-by-point inscription of fiber Bragg gratings using a femtosecond laser is highlighted. Fiber Bragg gratings with high spectral quality and strong first-order Bragg resonances within the C-band are achieved by optimizing the inscription process. Large birefringence (1.2x10(-4)) and high degree of polarization-dependent index modulation are observe...
متن کاملSimulation and Applications of Nonlinear Fiber Bragg Gratings
We have simulated the behaviors of nonlinear fiber Bragg gratings (FBGs). The generalized nonlinear equations governing these structures are solved by a method which uses a Fourier series procedure and a simple iterative method. All of the nonlinear effects are considered. Bragg soliton generation in intrinsic media and birefringence effects in FBGs are studied. We found that the first order di...
