“…An MZM-based optical frequency comb generator was recently demonstrated on a silicon chip [134]. Using this integrated comb, an 800 Gb/s superchannel (five carriers with 20-GBaud DP-QAM-16) was achieved, indicating a promising source solution for few-carrier superchannel transmitters.…”

The tremendous growth of data traffic has spurred a rapid evolution of optical communications for a higher data transmission capacity. Next-generation fiber-optic communication systems will require dramatically increased complexity that cannot be obtained using discrete components. In this context, silicon photonics is quickly maturing. Capable of manipulating electrons and photons on the same platform, this disruptive technology promises to cram more complexity on a single chip, leading to orders-of-magnitude reduction of integrated photonic systems in size, energy, and cost. This paper provides a system perspective and reviews recent progress in silicon photonics probing all dimensions of light to scale the capacity of fiber-optic networks toward terabits-per-second per optical interface and petabits-per-second per transmission link. Firstly, we overview fundamentals and the evolving trends of silicon photonic fabrication process. Then, we focus on recent progress in silicon coherent optical transceivers. Further scaling the system capacity requires multiplexing techniques in all the dimensions of light: wavelength, polarization, and space, for which we have seen impressive demonstrations of on-chip functionalities such as polarization diversity circuits and wavelength- and space-division multiplexers. Despite these advances, large-scale silicon photonic integrated circuits incorporating a variety of active and passive functionalities still face considerable challenges, many of which will eventually be addressed as the technology continues evolving with the entire ecosystem at a fast pace.

“…Chip-scale comb sources have been used in a variety of WDM transmission experiments, relying on different comb generation approaches and covering a wide range of data rates, channel counts, and line spacings [5][6][7][8][9][10][14][15][16][17][18][19]. A particularly promising option to generate frequency combs in chip-scale devices relies on Kerr comb generation in micro-ring resonators [27].…”

Optical frequency combs have the potential to become key building blocks of optical communication subsystems. The strictly equidistant, narrow-band spectral lines of a frequency comb can serve both as carriers for massively parallel data transmission and as local oscillator for coherent reception. Recent experiments have demonstrated the viability of various chip-based comb generator concepts for communication applications, offering transmission capacities of tens of Tbit/s. Here, we investigate the influence of the comb line power and of the carrier-to-noise power ratio on the performance of a frequency comb in a WDM system. We distinguish two regimes of operation depending on whether the comb source or the transmission link limits the performance of the system, i.e., defines the link reach, restricts the choice of modulation format and sets the maximum symbol rate. Finally, we investigate the achievable OSNR and channel capacity when using the tones of a soliton Kerr frequency comb as multi-wavelength carriers for WDM systems.

“…Combs generated in linear modulators have since been used in different configurations and applications for e.g. in Mach-Zehnder modulators(MZM) [17], cascaded MZM with phase modulators [8], dual-drive MZM [18], dual-parallel MZM configurations [19] etc.…”

We demonstrate a technique to continuously tune center frequency and repetition rate of optical frequency combs generated in silicon microring modulators and bandwidth scale them. We utilize a drive frequency dependent, microwave power induced shifting of the microring modulator resonance. In this work, we demonstrate center frequency tunability of frequency combs generated in silicon microring modulators over a wide range (∼8nm) with fixed number of lines. We also demonstrate continuously tunable repetition rates from 7.5GHz to 15GHz. Further, we use this effect to demonstrate a proof-of-principle experiment to bandwidth scale an 8-line (20dB band) comb generated from a single ring modulator driven at 10GHz to a comb with 12 and 15 lines by cascading two and three ring modulators, respectively. This is accomplished by merging widely spaced ring modulator resonances to a common location, thus coupling light simultaneously into multiple cascaded ring modulators.
