“…As an example, Figure 13F shows a stimulated FWM (sFWM) spectrum where an idler beam is spectrally translated into a signal beam. Intermodal FWM has been lately used to generate supercontinuum in multimode fibers [203] or in multimode waveguides [204,205] which allows facing the challenge to obtain a coherent and broadband source with nonlinear integrated optics [206].…”

Silicon Photonics, the technology where optical devices are fabricated by the mainstream microelectronic processing technology, was proposed almost 30 years ago. I joined this research field at its start. Initially, I concentrated on the main issue of the lack of a silicon laser. Room temperature visible emission from porous silicon first, and from silicon nanocrystals then, showed that optical gain is possible in low-dimensional silicon, but it is severely counterbalanced by nonlinear losses due to free carriers. Then, most of my research focus was on systems where photons show novel features such as Zener tunneling or Anderson localization. Here, the game was to engineer suitable dielectric environments (e.g., one-dimensional photonic crystals or waveguide-based microring resonators) to control photon propagation. Applications of low-dimensional silicon raised up in sensing (e.g., gas-sensing or bio-sensing) and photovoltaics. Interestingly, microring resonators emerged as the fundamental device for integrated photonic circuit since they allow studying the hermitian and non-hermitian physics of light propagation as well as demonstrating on-chip heavily integrated optical networks for reconfigurable switching applications or neural networks for optical signal processing. Finally, I witnessed the emergence of quantum photonic devices, where linear and nonlinear optical effects generate quantum states of light. Here, quantum random number generators or heralded single-photon sources are enabled by silicon photonics. All these developments are discussed in this review by following my own research path.

“…the key nonlinear process underlying SC generation in the anomalous dispersion region is noise-seeded modulation instability (MI) which breaks up the input pulse envelope into a train of hundreds sub-picosecond breather pulses with random characteristics (amplitude and duration) that subsequently undergo soliton dynamics similar to those observed in the short pulse regime [28]. In the normal dispersion regime, the SC develops from the combined effects of noise-seeded parametric four-wave mixing (FWM) processes assisted by cascaded Raman scattering (CRS) [29][30][31]. In multimode or birefringent fibers, the FWM processes can originate from phase-matched intermodal and vectorial nonlinear instabilities including polarization MI (PMI) and cross-phase MI (XPMI), respectively.…”

The physics and applications of fiber-based supercontinuum (SC) sources have been a subject of intense interest over the last decade, with a significant impact on both basic science and industry. New uses for SC sources are also constantly emerging due to their unique properties that combine high brightness, multi-octave frequency bandwidth, fiber delivery, and single-mode output. The last few years have seen significant research efforts focused on extending the wavelength coverage of SC sources towards the 2 to 20 μm molecular fingerprint mid-infrared (MIR) region and in the ultraviolet (UV) down to 100 nm, while also improving stability, noise, and coherence, output power and polarization properties. Here we review a selection of recent advances in SC generation in a range of specialty optical fibers including fluoride, chalcogenide, telluride, and silicon-core fibers for the MIR; UV-grade silica fibers, liquid-filled and gas-filled hollow-core fibers for the UV range; and all-normal dispersion fibers for ultra-low nose coherent SC generation.

“…Four-wave mixing is the main process that serves to generate SC in the visible part of the spectrum. Although recent experiments in multimode gradient-index (MM-GRIN) fibers [19,20] and few mode fibers [21][22][23] have also realized SC generation in strongly overlapping states, the very different behavior of the propagating modes, as well as having their anomalous dispersion spectrally near the pump wavelength, changes the dynamics of how modulation instability and the Raman continuum [20] aid in formation of the spectral power density.…”

In photonic crystal fibers, light guidance can be achieved by a central defect of a periodic structure of air holes in a silica glass matrix and the dispersion can be adjusted over a wide spectral range to enhance nonlinear effects. By coupling short pulse laser radiation into the core with tight confinement and utilizing the nonlinear properties of glass, this radiation can be converted to a broad spectral distribution. The tight confinement puts limits on the maximum pulse fluence propagating in the core due to the damage threshold of the glass. Therefore, when higher power spectral densities are desired, it is favorable to spread the generation of light over a much larger area to prevent fiber damage. We present here a method for generating a supercontinuum using the cladding modes of an endlessly single-mode fiber. These modes generate a supercontinuum utilizing a multimodal quasi-continuum of states, for which dispersion is governed by the guiding properties of the material between the air-filled holes in the cladding. The system also provides experimental access to unique phenomena in nonlinear optics. Simulations of the propagation properties of the core mode and cladding modes were compared with measurements of the group-velocity dispersion in a modified white-light Mach–Zehnder interferometer. The coupling of similar laser parameters into the cladding of the photonic crystal fiber enables a significant increase in conversion efficiency in the visible spectral range compared with the core-pumped case.
