Chirped Fiber Bragg Gratings for Optieal Fiber Dispersion Compensation

The use of α-power chirped fiber Bragg gratings for dispersion cancellation in an optical fiber link is discussed. Numerical and theoretical investigation of recompressing the dispersion-broadened pulse by using α-power chirped gratings is made, which shows that, the dispersion-broadened Gaussian pulse after 100 km standard fiber (with zero dispersion at λ = 1.3 μm) transmission at λ = 1.55 μm with initial width of TFWHM = 33ps (full width at …
