Paper Abstract

In this paper, all-optical wavelength conversion based on FWM in ROF system is theoretically analyzed. It can be used to generate the optical millimeter wave signals and to implement the all-optical frequency up/down conversion in ROF systems. Due to the ultrafast nonlinear response of the HNL-DSF, it is possible to realize terahertz waveform all-optical mixing or up-conversion. All-optical frequency up-conversions of an optical IF signal to the upper frequency band using FWM without serious crosstalk were demonstrated. Based on analysis of the all-optical wavelength conversion in high-nonlinear fiber, main factors related to the conversion efficiency are presented. Methods to increase the conversion efficiency have been discussed. With the longer high-nonlinear fiber, the higher nonlinear coefficient, the appropriate power of the pump, the appropriate polarization between the signal and the bump, and high efficiency to implement the wavelength conversion can be achieved. The theoretical analysis is verified by the simulation results.
