Dual-pump four-wave mixing for wavelength conversion is demonstrated using a distributed-feedback laser integrated with two electroabsorption modulators. The device acts as both the conversion medium and the dual-pump source. For a given input probe signal, output conjugate signal-to-noise ratio values of greater than 10 dB were measured over probe wavelengths ranging from 1557 to 1564 nm for a probe-conjugate detuning of 0.5 nm.
