Abstract

All-optical signal processing enables higher information transfer capacities at, potentially, low energy consumption [1]. Various types of functionalities such as switching, amplification, multiplexing, logic gates and buffers have already been demonstrated [1]. Previous signal amplification and restoration techniques have utilized phenomena such as FWM and Raman amplification, but have delivered fairly moderate amplifications from 5 dB to 11 dB [2,3]. Here, we experimentally demonstrate an all-optical photonic amplification technique that increases the signal-to-noise ratio by an unprecedented 46 dB. Our method is based on the nonlinear dynamics of soliton-dispersive wave interaction that occurs in supercontinuum (SC) generation in a photonic crystal fiber (PCF). We study the amplification dynamics across the full SC spectrum for varying degrees of SC coherence. Cross-correlation frequency resolved optical gating (XFROG) measurement unveils the role of the underlying soliton-dispersive wave interaction amplification mechanism.
