Paper Abstract
We demonstrate wavelength domain multiplexed (WDM) data transmission with a data rate of 14 Gbps based on optical
carrier generation with a single-section semiconductor mode-locked laser (SS-MLL) and modulation with a Silicon
Photonics (SiP) resonant ring modulator (RRM). 18 channels are sequentially measured, whereas the best recorded eye
diagrams feature signal quality factors (Q-factors) above 7. While optical re-amplification was necessary to maintain the
link budgets and therefore system measurements were performed with an erbium doped fiber amplifier (EDFA),
preliminary characterization done with a semiconductor optical amplifier (SOA) indicates compatibility with the latter
pending the integration of an additional optical filter to select a subset of carriers and prevent SOA saturation. A
systematic analysis of the relative intensity noise (RIN) of isolated comb lines and of signal Q-factors indicates that the
link is primarily limited by amplified spontaneous emission (ASE) from the EDFA rather than laser RIN. Measured RIN
for single comb components is below -120 dBc/Hz in the range from 7 MHz to 4 GHz and drops to the shot noise level at
higher frequencies.
