Asymmetrically Apodized Linearly Chirped Fiber Bragg Gratings for Efficient Pulse Compression

Abstract

Asymmetrically apodized linearly chirped fiber Bragg gratings (FBGs) are shown to have highly linearized time-delay response. In simulations of a five-stage, 5-cm grating-based dispersion compensation system, asymmetrically apodized FBGs are shown to give over 60% reduction in the energy scattered from the main pulse body, 16 ps - 60 ps pulses propagated over 800 km, as compared to a symmetrically apodized grating of similar length, strength, and bandwidth.
