WebMar 6, 2024 · This paper proposes a system that aims to reduce the spectral width, Δλ, of the optical signal at transmitter for WDM system over distance 100 km. Also, a chirped fiber Bragg grating (CFBG) at the receiver is used to compensate dispersion. The proposed system consists of four cascaded FBGs connected between light source and optical … Webharmonic, which is excited at an infinitely large grating with grating period λ p and grating vector k pp= 2πλ.{xyz′′ ′,,}is the reference frame for a particle moving parallel to the grating surface, hence z′=z. ψ is the angle between k p and the particleʼs velocity v; φ is the angle between the propagation direction k ∥ of the ...
