The Effect of Profile Noise on the Spectral Response of Fiber Gratings

Abstract

Fiber Bragg gratings are now finding more and more commercial applications, particularly in Wavelength-Division-Multiplexed (WDM) optical communication systems. For such systems, the fiber grating response must meet stringent requirements of wavelength accuracy, stability, bandwidth, channel isolation and, for dispersion compensators, group delay ripple. It is important for fiber grating manufacturers to understand the factors that can degrade the response of a fiber grating, and what tolerances this places on the manufacturing system.
