Claim Text:
1. A wavelength converter, comprising: first silicon waveguides; second silicon waveguides intersecting the first silicon waveguides to form an arrayed waveguide, the arrayed waveguide configured to receive optical data signals at the same wavelength at a first input and optical pump signals at different wavelengths at a second input; microring resonators evanescently coupling different ones of the first silicon waveguides to different ones of the second silicon waveguides, each microring resonator tuned to the wavelength of the optical data signals or one of the wavelengths of the optical pump signals, so that different combinations of the optical data signals and the optical pump signals are provided at an output of the arrayed waveguide, wherein each combined optical signal has a composite wavelength comprising the wavelength of the optical data signal and one of the wavelengths of the optical pump signals; and a non-linear optical media configured to convert the composite wavelength of each combined optical signal at the output of the arrayed waveguide to yield wavelength converted signals each having a new dedicated wavelength.
