“…The generation of ultrabroadband supercontinuum (SC) spectra has now been demonstrated by several groups by injecting high power pulses near the zero dispersion wavelength of photonic crystal fibers (PCF) [1,2]. Similar broadband SC have also been observed in standard optical fiber tapered to a strand diameter~2 µm where the tapering introduces dispersion and nonlinearity characteristics similar to those of PCF [3]. Numerical simulations of such SC generation have also recently been reported, leading to an improved understanding of the underlying spectral broadening mechanisms involved [4][5][6][7][8].…”

Numerical simulations are used to study the temporal and spectral characteristics of broadband supercontinua generated in photonic crystal fiber. In particular, the simulations are used to follow the evolution with propagation distance of the temporal intensity, the spectrum, and the cross-correlation frequency resolved optical gating (XFROG) trace. The simulations allow several important physical processes responsible for supercontinuum generation to be identified and, moreover, illustrate how the XFROG trace provides an intuitive means of interpreting correlated temporal and spectral features of the supercontinuum. Good qualitative agreement with preliminary XFROG measurements is observed.

“…Although supercontinuum sources with structured optical fibres of various sorts has proven to be successful, they are clearly not the only means of generating these -dispersion compensating fibres were recognised long ago for this application [Wai et al 1986], as were tapered conventional silicate fibres and nanowires [Birks et al 2000;Lu & Knox 2004] designed to increase the intensity and lower the threshold and interaction length for the various nonlinear phenomena. Further, many numerous solid liquid and gaseous media with very high nonlinear coefficients make better, compact and cheaper sources generally.…”

Structured optical fibres are commonplace within optical research since many phenomena can, in the first instance, be localised and studied with greater ease within the confines of an optical waveguide, seemingly offering many alternative approaches to other existing technologies. However, this apparent ease has not translated to actual technology penetration beyond a few (but important) niche areas, with their superiority over existing technologies being unclear. Here, the linear and nonlinear properties possible with these structured fibres is reviewed and evaluated, both from a scientific and applied perspective. A case for citing complex and multiple functionality as an important motivation leading to future new technology is presented.

“…The SC generation mechanism has been recently recognized as a sequence of nonlinear physical processes, each occurring consecutively along the propagation axis such as self-phase modulation (SPM), self-steepening (SS), stimulated Raman scattering (SRS), and four-wave mixing (FWM) [4]. The first SC generation experiments in silica were obtained by standard optical fiber with zero group velocity dispersion (GVD) wavelength around 1.3 µm and several hundred meters of the fiber length [5]. The advent of photonic crystal fibers (PCFs) in the form of triangle and square lattices at the late 1990s attracted widespread interest throughout the scientific community, and has led to a revolution in the generation of ultra-broadband high brightness spectra through SC generation [6][7][8].…”

In this paper, a square-lattice photonic crystal fiber based on optofluidic infiltration technique is proposed for supercontinuum generation. Using this approach, without nano-scale variation in the geometry of the photonic crystal fiber, ultra-flattened near zero dispersion centered about 1500 nm will be achieved. By choosing the suitable refractive index of the liquid to infiltrate into the air-holes of the fiber, the supercontinuum will be generated for 50 fs input optical pulse of 1550 nm central wavelength with 20 kW peak power. We numerically demonstrate that this approach allows one to obtain more than two-octave spanning of supercontinuum from 800 to 2000 nm. The spectral slicing of this spectrum has also been proposed as a simple way to create multi-wavelength optical sources for dense wavelength division multiplexing.
