“…Terabit/s super-channel transmission has been demonstrated before, using different approaches for realizing the optical source. These approaches include ensembles of independent lasers [11,12], single-laser concepts with sidebands generated by external modulation [13,14] or by Kerr comb generation in optically nonlinear high-Q microresonators [15], and fiber-based spectral broadening [5,9,[16][17][18]. Arrays of independent lasers offer flexibility and do not require filters for spectrally separating the comb lines.…”

“…Kerr comb sources can provide a large numbers of lines, but require sophisticated pumping schemes and the line spacing is inherently tied to the free spectral range of the underlying resonator. Broadband frequency combs for terabit/s superchannels can also be generated by solid-state mode-locked lasers in combination with highly nonlinear fibers [5,9,20], or multi-stage parametric mixers [16][17][18]. However, both approaches require strong optical pumps and large interaction lengths in delicately arranged sequences of specialized optical fibers.…”

Terabit/s super-channels are likely to become the standard for next-generation optical networks and optical interconnects. A particularly promising approach exploits optical frequency combs for super-channel generation. We show that injection locking of a gain-switched laser diode can be used to generate frequency combs that are particularly well suited for terabit/s super-channel transmission. This approach stands out due to its extraordinary stability and flexibility in tuning both center wavelength and line spacing. We perform a series of transmission experiments using different comb line spacings and modulation formats. Using 9 comb lines and 16QAM signaling, an aggregate line rate (net data rate) of 1.296 Tbit/s (1.109 Tbit/s) is achieved for transmission over 150 km of standard single mode fiber (SSMF) using a spectral bandwidth of 166.5 GHz, which corresponds to a (net) spectral efficiency of 7.8 bit/s/Hz (6.7 bit/s/Hz). The line rate (net data rate) can be boosted to 2.112 Tbit/s (1.867 Tbit/s) for transmission over 300 km of SSMF by using a bandwidth of 300 GHz and QPSK modulation on the weaker carriers. For the reported net data rates and spectral efficiencies, we assume a variable overhead of either 7% or 20% for forward-error correction depending on the individual sub-channel quality after fiber transmission.

“…As cost and energy consumption are becoming limiting factors in high-capacity systems, using fewer lasers with less energy consumption grows desirable and demonstrations of ultra-high-capacity optical transmission based on nonlinear fiber based spectral broadening of a seed laser frequency comb have been reported 1,2,3,4 . The prospect of moving the fiber-based frequency comb sources onto a photonic chip platform holds many attractive features, including ultra-high bandwidth, stable polarization and phase, absence of stimulated Brillouin scattering (SBS), and the possibility of photonic integration with a seed laser 5 .…”

We experimentally demonstrated 10 GHz frequency comb spectral broadening in an AlGaAsOI nano-waveguide with the peak power of only several watts. The spectral broadened 10 GHz frequency comb has high optical signal to noise ratio (OSNR) at the output of the nano-waveguide. As far as we know, it is the first photonic chip based frequency comb, relying on spectral broadening of a 10 GHz mode-locked laser comb in an AlGaAsOI nano-waveguide, with a sufficient comb output power to support several hundred Tbit/s optical data.
