摘要：
The paper presents a high nonlinear photonic crystal fiber (HN-PCF) with highly duty ratio for time-stretch analog-to-digital conversion (TSADC). The simulation results show that a nonlinear of 42.26 W-1 km(-1) and the flattened dispersion of less than 1.0 ps/(nm km) are obtained in more than 495 nm waveband (1205-1700 nm). Owing to its high nonlinear coefficient and flattened dispersion, the high nonlinear PCF is expected to be suitable for supercontinuum (SC) generation. The numerical simulation results demonstrate that the proposed high duty ratio HN-PCF can generate wideband SC. (C) 2014 Elsevier GmbH. All rights reserved.
