Generation of supercontinuum bottle beam using an axicon
Optics Express, 2007 A supercontinuum bottle beam was successfully produced by focusing a supercontinuum laser beam after passing through an axicon. The supercontinuum radiation was generated from a microstructured fiber pumped by a self-kerr-lens mode-locked femtosecond Ti:sapphire laser. The cross-section intensity distributions of the generated bottle were recorded by a

Sulfadiazine selection enables high‐efficiency transformation in Nannochloropsis and Microchloropsis
The Plant Journal, Volume 127, Issue 3, August 2026.SUMMARY Nannochloropsis and Microchloropsis are important as eustigmatophyte model organisms and the production of high‐value lipids. Efficient selectable markers are indispensable for genetic engineering to study and improve production yield of these species.

Exceptional Light Propagation via Generalized Bulk‐Edge Correspondence
Nanophotonics, Volume 15, Issue 13, 13 July 2026.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
Nanophotonics, Volume 15, Issue 13, 13 July 2026.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

Manipulating the Propagation of Solitons with Solid-Core Photonic Bandgap Fibers
International Journal of Optics, 2012 We review the dynamics of soliton self-frequency shift induced by Raman gain in special solid-core photonic bandgap fibers and its consequences in terms of supercontinuum generation.

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy
Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.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.
