Paper Abstract
The innovation of optical frequency combs (OFCs) generated in passive mode-locked lasers has provided astronomy
with unprecedented accuracy for wavelength calibration in high-resolution spectroscopy in research areas such as the
discovery of exoplanets or the measurement of fundamental constants. The unique properties of OCFs, namely a highly
dense spectrum of uniformly spaced emission lines of nearly equal intensity over the nominal wavelength range, is not
only beneficial for high-resolution spectroscopy. Also in the low- to medium-resolution domain, the OFCs hold the
promise to revolutionise the calibration techniques. Here, we present a novel method for generation of OFCs. As
opposed to the mode-locked laser-based approach that can be complex, costly, and difficult to stabilise, we propose an
all optical fibre-based system that is simple, compact, stable, and low-cost. Our system consists of three optical fibres
where the first one is a conventional single-mode fibre, the second one is an erbium-doped fibre and the third one is a
highly nonlinear low-dispersion fibre. The system is pumped by two equally intense continuous-wave (CW) lasers. To be
able to control the quality and the bandwidth of the OFCs, it is crucial to understand how optical solitons arise out of the
initial modulated CW field in the first fibre. Here, we numerically investigate the pulse evolution in the first fibre using
the technique of the solitons radiation beat analysis. Having applied this technique, we realised that formation of higherorder
solitons is supported in the low-energy region, whereas, in the high-energy region, Kuznetsov-Ma solitons appear.
