Stimulated Raman Scattering with Optical Vortex Beams

open access: yesAdvanced 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.

Tuning Surface Phonon Polaritons in One‐Dimensional Complementary Nanostructures via Curvature and Dielectric

open access: yesAdvanced Photonics Research, EarlyView.
Curvature and dielectric is introduced to tune properties of surface phonon polaritons (SPhPs) in complementary nanostructures: nanowire (NW) and nanohole (NH). It is found that NH complements the frequency band range of SPhP of NW. Frequency‐band subinterval of the SPhP in NHs and NWs can be tuned by dielectric.
