“…[29] We also anticipate broader implications of this work beyond analog gravity. Recent research in linear and nonlinear optics of hyperbolic metamaterials [30][31][32] continues to bring about novel and interesting developments, such as squeezing of hyperbolic polaritonic rays in cylindrical lamellar structures, [33] which may find potential applications in solar cells and spectroscopy, as well as recent proposal of novel optical limiting and hypercomputing devices based on nonlinear optics of photonic hypercrystals. [34] The reported experiments provide much-needed experimental feedback to this recent theoretical body of work on nonlinear optics of hyperbolic metamaterials.…”

Recent theoretical and experimental work demonstrated that nonlinear optics of ferrofluid‐based hyperbolic metamaterials exhibit very unusual spatiotemporal dynamics. Here a detailed theoretical and experimental study of mutual interactions of individual self‐focused optical filaments inside this metamaterial is reported. In agreement with theoretical expectations, the observed mutual interactions of individual filaments exhibit strong similarities with general relativity in 2+1 dimensions, which predicts that these interactions must have predominantly non‐Newtonian topological character. This observation is important since 2+1‐dimensional gravity is an exactly solvable theory even in the quantum gravity limit.

“…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.

“…Therefore, the refractive index difference between the waveguide core and substrate and the dispersion characteristic can be flexibly changed. In addition, its large transparency window (more than 15 μm [26], more than twice that of Si) and strong Kerr nonlinear index (on the order of 10 -17 m 2 /W [27], an order of magnitude larger than that of Si [28]) make it suitable for the mid-infrared SC generation. Mei designed the AlGaAs strip waveguides to generate the broadband SC, spanning from 2 to 15.9 μm [29].…”
