A novel and quite simple all-optical wavelength converter using a single-mode Fabry-Pe??rot laser diode (SM FP-LD) is proposed. The working principle is explained and the experimental results at 10 Gb/s are demonstrated. The wavelength conversion is realized based on injection-locking and the modulation of self-locking state of the SM FP-LD by an external pump injection. The converted signals show about an 11-dB extinction ratio and a sidemode suppression ratio (SMSR) of 43 dB in static measurement. We measured the bit-error-rate (BER) performances and error-free conversions were observed. A power penalty of less than 1 dB at a BER of 10-9 was measured, for two different input wavelengths conversion.
