In this paper, we present a simple, efficient, and cost-effective all-optical wavelength converter using injection-induced wavelength switching in widely tunable V-cavity laser. When an external signal beam is injected at a wavelength corresponding to one of the sidemodes with a small detuning of about 0.1 nm, the lasing wavelength is switched from the original main mode to the side mode. By filtering out the main mode of the V-cavity laser, a data-inverted wavelength conversion is achieved. This wavelength converter can offer a non-return-to-zero (NRZ) channel-to-channel conversion with converted signal approximately at 200 GHz away from the input signal. A 2.5 Gb/s non-return-to-zero (NRZ) conversion is experimentally demonstrated with an extinction ratio over 4 dB and SMSR of 36 dB.
