Studies on Chirped Fiber Bragg Grating and Its Application for Dispersion Compensation in Optical Communication Systems

摘要

Chirped fiber Bragg grating (FBG) is one of most attractive component for chromatic dispersion compensation. In this paper, we discuss the possible factors that affect the characteristics of chirped fiber grating made by phase mask technique, including collimating of writing laser beam, growing rate and using non-zeroth-order suppression diffraction phase-mask. Meanwhile, the experimental results show that a l0cm-long chirped fiber grating fabricated through this processing was reasonably feasible for chromatic dispersion compensation in l0Gbit/s transmission system.
