  We demonstrate a stable CMOS-compatible on-chip multiple-wavelength source by
filtering and modulating individual lines from a frequency comb generated by a
microring resonator optical parametric oscillator.. We show comb operation in a
low-noise state that is stable and usable for many hours. Bit-error rate
measurements demonstrate negligible power penalty from six independent
frequencies when compared to a tunable diode laser baseline. Open eye diagrams
confirm the fidelity of the 10 Gb/s data transmitted at the comb frequencies
and the suitability of this device for use as a fully integrated silicon-based
WDM source.
