All-Optical Wavelength Conversion Using Four-Wave Mixing in Optical Fiber

Abstract

All-optical wavelength conversion is one of the key technologies in constructing future photonic networks. Among many candidates, four-wave mixing in an optical fiber is especially attractive for realizing inherently broadband and modulation-transparent wavelength converters. This paper summarizes the recent research advances of wavelength converter based on fiber four-wave mixing. We first review the basic principle of four-wave mixing in an optical fiber. Then we introduce latest experimental results and discuss design strategies as well as challenges.
