Abstract
A wavelength converter includes first silicon waveguides and second silicon waveguides intersecting the first silicon waveguides to form an arrayed waveguide. The arrayed waveguide receives 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 couple different ones of the first silicon waveguides to different ones of the second silicon waveguides. Each microring resonator is 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. A non-linear optical media converts the wavelength of each combined optical signal at the output of the arrayed waveguide to yield wavelength converted signals each having a new dedicated wavelength.
