This paper describes the selective wavelength conversion of 2.5 G-b/s optical packets from the light of a Fabry-Perot laser-diode (FP-LD) to the light of an ITU-T grid wavelength. This is an example of application of the cross-phase modulation (XPM) type wavelength converter to future photonic networks in which optical signal sources without wavelength control is used at user-end terminals. We fabricated an XPM wavelength converter module by using hybrid integration technique. The module consists of a semiconductor optical amplifier (SOA) array and planar-lightwave-circuit (PLC) waveguide. We confirmed the good feasibility of the selective wavelength conversion and 80-km transmission on single-mode fiber (SMF) after the wavelength conversion without any signal degradation.
