    Period of long-period fiber gratings

    A long-period fiber grating (LPG) is a one dimension (1D) periodic structure, and is formed by introducing periodic modulation of the refractive index along an optical fiber. The coupling from the guided mode to cladding modes is wavelength dependent so we can obtain a spectrally selective loss. It is an optical fiber. In essence, a long period fibre grating (LPFG) is an all-fibre device with wavelength dependent loss. As a band rejection filter, all light in a spectral slice is discarded without affecting the amplitude and phase of neighbouring wavelengths, with the additional advantage of low insertion losses. Long period fiber gratings (LPFGs) were fabricated in a standard single mode fiber (SMF-28e) through femtosecond (fs) laser direct writing. Firstly, the techniques of fabricating HLPGs by CO 2 laser, hydrogen–oxygen flame heating, and arc discharge are summarized.

    Fiber Bragg grating chirp effect

    The simulation results show that the gradient temperature distribution in the FBG axis can induce spectral chirps of FBG. The increase in the bandwidth of the spectrum and the decrease in the reflection intensity are caused by the rise of the temperature gradient. Fiber Bragg Gratings (FBGs) are one of the most popular technology within fiber-optic sensors, and they allow the measurement of mechanical, thermal, and physical parameters. In recent years, a strong emphasis has been placed on the fabrication and application of chirped FBGs (CFBGs), which are. In this paper, a theoretical analysis of recently developed tapered chirped fiber Bragg gratings (TCFBG) written in co-directional and counter-directional configurations is presented. This paper analyzes the principles of linear chirped fiber gratings and nonlinear chirped fiber gratings, and on the basis of summarizing. A scheme comprising only four optimized linearly chirped fiber Bragg gratings (LCFBGs) is proposed for compensating the dispersion effects in 48 × 20 Gbps DWDM system.
