“…First obtained in a bulk glass and then in a wide variety of nonlinear media including optical fibres, SC generation refers to the process through which relatively narrowband optical signals suffer extreme spectral broadening as a result of the combination and interaction of nonlinear optical phenomena such as self-phase modulation (SPM), cross-phase modulation (XPM), stimulated Raman scattering (SRS), four-wave mixing (FWM), modulation instability (MI) and fission of higher-order solitons (HOS), as it has been published on the subject [2,3]. The interest to continue developing supercontinuum light sources relies mainly on their potential applications, which include telecommunications [4], optical pulse compression [5], sensing and microscopy [6], and imaging [7].…”

We present a systematic experimental study of supercontinuum (SC) spectra produced by propagating noise-like pulses (NLPs) from an erbium-doped figure-eight laser through sections of different lengths of standard single-mode fibre (SMF) and of high-nonlinearity fibre (HNLF), as well as their combinations. With an average input power that does not exceed 35 mW, very broad and smooth SC spectra extending over several hundreds of nm are typically observed, even when only SMF is used. However, maximal broadening and flatness are obtained through a section of about 300 m of SMF followed by 50 m of HNLF; the spectrum then spans from ~1260 nm up to ~2070 nm, with a bandwidth of 431 nm at 5.7 dB from the maximum (over 800 nm at 20 dB). Our analysis indicates that nonlinear processes are still operating even after propagation through several hundreds of meters of fibre, extending and flattening the spectrum, its maximal bandwidth being eventually limited by the strong fibre attenuation in the 2 µm region.

“…It was first witnessed in 1970 by two person named Shapiro and Alfano [ 1 ]. This continuum belongs to a wide range of applications in telecommunication [ 2 ], optical frequency metrology [ 3 ], molecular spectroscopy [ 4 ], optical coherence tomography [ 5 ], optical frequency comb generation [ 6 ], biomedical purposes [ 7 ] etc.…”

“…Supercontinuum (SC) generation is a process that allows the emission of broadband spectrum with bandwidth many times wider than the spectrum of pumping light. SC generation involves multiple nonlinear phenomena such as self-phase modulation (SPM), cross-phase modulation (XPM), stimulated Raman scattering (SRS), four-wave mixing (FWM), modulation instability (MI) and fission of higher-order solitons (HOS), which makes the dynamics of the SC generation quite complicated [1,2]. SC generation is of great interest due to its potential application in many areas [3][4][5][6][7][8].…”

“…The properties of light interacting with the nonlinear medium determine the SC properties. In the case of continuous-wave pumping, the efficiency of spectral broadening is much lower than in the case of pulses [1,2]. Therefore, SC is generated typically using high-intensity femtosecond pulses [21] and can also be produced easily by nanosecond pulses [22,23].…”

We report an experimental study of the supercontinuum (SC) generated by molecules of solitons (MS) and noise-like pulses (NLP) and their dependence on pump power in two different types of optical fibers: 500 m of standard fiber (SMF-28, Corning) and 100 m of high-nonlinearity fiber with a zero-dispersion slope (Furukawa HNLF-ZS). Our results show a more complex dependence of the SC spectra on pump power for the MS than for the NLP used for pump. We attribute such differences to soliton fission of MS whereas this process is already done within the NLP. We use a nonlinear optical loop mirror (NOLM) connected to the output of the fiber under test to evaluate the amplitude of ultrashort pulses, which compose SC and found that amplitude is changed strongly throughout the spectrum. The NOLM suppresses pulses with low peak power, this is especially pronounced for wavelengths longer than ∼1750 nm for both fibers, and in the region between 1450 nm–1640 nm for the high-nonlinearity fiber.
