We demonstrate that broad-area vertical-cavity semiconductor optical amplifiers allow for wavelength conversion at 2.5 Gb/s via cross-gain modulation (XGM). XGM is reached with a saturation beam of only 1.5 mW over an optical bandwidth of 0.7 nm (215 GHz). Depending on the wavelengths of the injected fields, inverted or noninverted output can be obtained.
