Abstract
An optical wavelength converter based on cross-gain modulation with wide input dynamic range, the converter including a semiconductor optical amplifier, a continuous wave source, and a probe beam controller. The semiconductor optical amplifier modulates probe power on the basis of pump power. The continuous wave source generates the probe beam and supplies the generated probe beam to the semiconductor optical amplifier. The probe beam controller adjusts bias current supplied to the continuous wave source and controls the probe power in proportion to the pump power.
