Demonstration of Broadband Wavelength Conversion at 40 Gb/s in Silicon Waveguides

We present ultra-broadband wavelength conversion in silicon photonic waveguides at a data rate of 40 Gb/s. The dispersion-engineered device demonstrates a conversion bandwidth spanning the entire S -, C -, and L -bands of the ITU grid. Using a continuous-wave C -band pump, an input signal of wavelength 1513.7 nm is up-converted across nearly 50 nm at a data rate of 40 Gb/s, and bit-error-rate measurements are performed on the converted signal.
