Stimulated Raman Scattering with Optical Vortex Beams

Advanced Photonics Research, EarlyView.
This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.

Precision Construction of Chiral Optical Fields with Nine Controllable Degrees of Freedom

Advanced Photonics Research, EarlyView.
Chiral optical fields (COFs) offer multiple controllable degrees of freedom (DOFs), enabling applications in optical tweezers, manufacturing, and encryption. However, achieving precise sidelobe control remains a challenge. This work introduces a modular multilayer annular phase plate to fine‐tune COFs by manipulating nine DOFs.

Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms

Advanced Photonics Research, EarlyView.
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion
