Paper Abstract

All-optical wavelength converter is demonstrated by using a SOA-based fiber ring laser and an asymmetric Mach-Zehnder interferometer (AMZI). There is no need for an additive probe beam source in this configuration and the output beam from the fiber ring laser will be utilized as the probe beam to complete a wavelength conversion. The operation principles of the all-optical wavelength conversion with the proposed configuration are analyzed theoretically. In this analytical process the steady-state and gain-modulated oscillations of the fiber ring laser with and without the input signal beam are described, respectively. Also the operation principle of the AMZI to convert a phase-modulated signal into an intensity-modulated one is introduced. An experimental system and its performances as well as some measured results, such as time waveforms, extinction ratios and bit-error rates, are demonstrated. Some discussions also are given.
