Supercontinuum generation in 1-decanol
Although solids have been recently used in ultrafast experiments for spectral broadening due to their relatively high nonlinearity, their sensitivity to damage limits their long-term stability. Liquids are a possible alternative to solids as a nonlinear medium because of their comparable nonlinearity and resistance to permanent ...

Transverse mode instability (TMI) is a primary limitation for power scaling in high-brightness fiber lasers. This paper reports observation of the TMI effect in the process of supercontinuum generation, and demonstrates a 993 W linearly polarized ...

Exceptional Light Propagation via Generalized Bulk‐Edge Correspondence
We show that unlike in electronic systems, localized edge states in topological photonics are governed not only by nontrivial bulk topology, but also by polarization‐dependent light‐line confinement conditions inherent to Maxwell's equations. This fundamentally generalized bulk‐edge correspondence unlocks new regimes of tunable near‐cutoff localization

Wavelength and Polarization Multiplexed Nonlocal Metasurface for Quantitative Phase Microscopy
A nonlocal metasurface with wavelength and polarization multiplexed optical transfer functions is demonstrated for performing quantitative phase imaging. The metasurface uses the angular dispersion of optical routing guided mode resonances to extract phase gradient information along different directions for phase retrieval. ABSTRACT Imaging transparent

Machine learning analysis of rogue solitons in supercontinuum generation
Supercontinuum generation is a highly nonlinear process that exhibits unstable and chaotic characteristics when developing from long pump pulses injected into the anomalous dispersion regime of an optical fiber.

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy
The depicted thermally activated delayed fluorescence (TADF) emitter was studied by femtosecond near‐infrared (NIR) spectroscopy. A prominent NIR transition was shown to be strongly solvent‐dependent, with implication for intersystem crossing in the compound.

Active Hyperspectral Sensor Based on MEMS Fabry-Pérot Interferometer
An active hyperspectral sensor (AHS) was developed for target detection and classification applications. AHS measures light scattered from a target, illuminated by a broadband near-infrared supercontinuum (SC) light source.

Stimulated Supercontinuum Generation
We demonstrate active control over optical rogue waves with a weak optical seed. With this effect, we stimulate supercontinuum generation, resulting in greatly enhanced stability and coherence. The phenomenon also facilitates all-optical three-terminal devices.

Supercontinuum generation in the ultraviolet (UV) spectral region is challenging in solid-core optical fibres due to solarisation and photodarkening. Antiresonant hollow-core fibres have overcome this limitation and have been shown to guide UV light at ...

We present an all-fiber coherent supercontinuum spanning the spectral range of 1.7–5.0 µ m from a cascade of silica, ZBLAN, and chalcogenide (ChG) nonlinear fibers (NLFs).
