“…The circular lattice with high geometric symmetry can effectively confine the electromagnetic field in the core, enhancing the nonlinearity of the fiber. Furthermore, PCFs with circular lattices also expose good applicability in spectroscopy, pulse compression, dense wavelength division multiplexing-based telecommunication systems, and sensing applications [40,42]. In this work, we verify, for the first time, the potential to generate the broadband mid-infrared SCGs with peak powers lower than 300 W using C 6 H 6 -filled core circular lattice PCFs.…”

This article introduces a new model of a circular silica-based photonic crystal fiber with a hollow core filled with C6H6. The difference in the air hole size and the distance between them in the first ring around the core has a profound effect on the dispersion, leading to ultra-flat dispersion with values as low as ±0.996 ps nm−1· km in wavelength range 0.74 µm. The high nonlinear coefficient of several 1000 W−1 · km−1 and the low confinement loss of a few tens of dB m−1 suggest proposing three fibers with dispersion and nonlinear properties suitable for broadband supercontinuum generation at low peak power. The influence of peak power on the broadening of the supercontinuum spectrum is also investigated. Fibers with a flat all-normal dispersion profile provide a smooth spectrum with bandwidths of 1.215 and 1.626 µm at 30 dB with a peak power of 250 W. A fiber with an anomalous dispersion regime generates a supercontinuous spectrum, broadening to 3.868 µm in the mid-infrared region (2.467 µm bandwidth at 30 dB) under laser pulse excitation with 130 W peak power. Our results provide further insights into the generation of broadband mid-infrared supercontinuum using liquid-core silica-fibers, which have great potential for applications in the fields of optical communications and optical sensing.

“…The analysis of the coherence of SC spectra was absent in their study. Another composite fiber with silicon core and MgF 2 cladding has been reported [ 23 ] for SC generation of about 2670 nm spanning. However, the spectral bandwidth achieved is not worthy enough in comparison to other composite PCF.…”

The understanding of light-matter interaction processes has been essential for the attainment of many modern advancements in photonics, for instance the telecom revolution with lasers and fiber optics. Thereby, related industries greatly benefit from large availability of professionals, qualified for undertaking projects focused on devising and scaling products that may capitalize scientific progress on photonic materials and novel optical effects. Nevertheless, the familiarity with the application of these phenomena is usually gained by scientists and engineers at graduate education level, which commonly leads to a skilled workforce shortage. This lack of photonic-capable engineers becomes more critical when discussing nonlinear and quantum applications that will be broadly available soon. With this motivation, we present a nonlinear photonics hands-on training that could be integrated into curricula for photonics engineers or material scientists. The proposed session is aimed at undergraduate students, who would develop through practical experience relevant multidisciplinary skills for experimental design, data acquisition, setup configuration and optical alignment. Manuals are provided for the implementation of Z-Scan technique in the characterization of nonlinear optical materials. Equipment requirements are included along with the undergraduate-level theoretical content that may serve as introduction for students without prior exposure to nonlinear optics. Additionally, an open-source python-based software is provided for simplifying the extraction of Kerr effect and two-photon absorption figures of merit by means of the analysis of power measurements.
