Theoretical and experimental performance evaluation of all-optical multiwavelength conversion by four-wave mixing in fiber at 10/20/40 Gb/s for optical layer multicast

Abstract

All-optical multiwavelength conversion (MWC) enables optical layer multicast without electronic processing. Wavelength conversion by four-wave-mixing (FWM) offers strict transparency in bit rate and modulation format. In this letter, a novel FWM MWC scheme is proposed, supported by theoretical analysis and experimental performance evaluation at 10/20/40 Gb/s. © 2007 Wiley Periodicals, Inc.
