“…The FoM of a nonlinear mixer is defined as the product of optical power (P), effective interaction length (L) and mixer nonlinearity (γ) [145]. Wide-band phase matching is essential to maintain a high FoM, because not only are the optical pulses with high peak power required, but also the peak power of the pulses should remain high, while propagating inside the nonlinear material.…”

“…Myslivets et al introduced two CW tones as a seed that can be easily tuned to produce an arbitrary comb frequency pitch and demonstrated a new mixer architecture based on 'chirp-compress-and-mix cycle' for wideband comb generation as depicted in Fig. 17 (b) [145]. The new architecture relies on the efficient creation of higherorder mixing tones in phase-matched nonlinear fiber stages, separated by a linear compressor.…”

“…However, the compression process is not ideal and its imperfection leading to parasitic side-lobes, causing interference. The side-lobes prevent the generation of a flat top intensity pulse, which results in spectral ripple (poor flatness) [86], [145]. The output of the SMF is then passed through the second nonlinear mixer stage (NL 2 ), where four photon mixing interaction produces a wideband OFC.…”

Abstract-Elastic optical networks (EON) have been proposed to meet the network capacity and dynamicity challenges. Hardware and software resource optimization and re-configurability are key enablers for EONs. Recently, innovative multi-carrier transmission techniques have been extensively investigated to realize high capacity (Tb/s) flexible transceivers. In addition to standard telecommunication lasers, optical carrier generators based on optical frequency combs (OFC) have also been considered with expectations of reduced cost and inventory, improved spectral efficiency and flexibility. A wide range of OFC generation techniques have been proposed in the literature over the past few years. It is imperative to summarize the state of the art, compare and assess these diverse techniques from a practical perspective. In this survey, we identify salient features of optical multicarrier generators, review and compare these techniques both from a physical and network layer perspective. OFC demultiplexing/filtering techniques have also been reviewed. In addition to transmission performance, the impact of such sources on the network performance and real-world deployment strategies with reference to cost, power consumption, and level of flexibility have also been discussed. Field trials, integrated solutions, flexibility demonstrations are also reported. Finally, open issues and possible future directions that can lead to real network deployment are highlighted.

“…A frequency comb synthesis can also be accomplished with the technique of parametric process. [10][11] With this method, OFCs with more than 120 tones in a 100 nm-wide continuous band have been generated. 12 When the pumps for the parametric process are phase-correlated by injection locking, the spectral linewidth broadening inherent to parametric comb generation can be cancelled.…”

ABSTRACT* This paper describes the frequency comb generation in a parametric mixer based on a section of highly nonlinear fiber (HNLF), and spectral linewidth characteristics of the generated parametric comb lines are investigated for the first time. In the experiments, the parametric mixer is driven by electro-optical modulated continuous-wave, and combs with about 40 lines are obtained. The linewidth of the tones with different orders is measured. The results show that the parametric comb lines are characterized with spectral linewidth preservation.

“…This approach has been already extensively studied with the aim to generate ultra-short pulses at high repetition rates [4,5,6,7,8,9,27]. But also some approaches specifically targeting the task of the OFC generation in highly nonlinear fibres were numerically and experimentally studied in the recent past [28,29,30].…”

Generation of optical frequency combs via four-wave mixing processes for low- and medium-resolution astronomy

We investigate the generation of optical frequency combs through a cascade of four-wave mixing processes in nonlinear fibres with optimised parameters. The initial optical field consists of two continuous-wave lasers with frequency separation larger than 40 GHz (312.7 pm at 1531 nm). It propagates through three nonlinear fibres. The first fibre serves to pulse shape the initial sinusoidal-square pulse, while a strong pulse compression down to sub-100 fs takes place in the second fibre which is an amplifying erbium-doped fibre. The last stage is a low-dispersion highly nonlinear fibre where the frequency comb bandwidth is increased and the line intensity is equalised. We model this system using the generalised nonlinear Schrödinger equation and investigate it in terms of fibre lengths, fibre dispersion, laser frequency separation and input powers with the aim to minimise the frequency comb noise. With the support of the numerical results, a frequency comb is experimentally generated, first in the near infra-red and then it is frequency-doubled into the visible spectral range. Using a MUSE-type spectrograph, we evaluate the comb performance for astronomical wavelength calibration in terms of equidistancy of the comb lines and their stability.
