Anomalous blue-shift of terahertz whispering-gallery modes via dielectric and metallic tuning
Optics Letters, 2019 The vast majority of resonant systems show a red-shift for the resonance frequency when a perturbation, e.g. losses, are introduced to the system. In contrast, here we report for the first time the experimental demonstration of both red- and anomalous ...

Relation between Halogen Bond Strength and IR and NMR Spectroscopic Markers
Molecules, 2023 The relationship between the strength of a halogen bond (XB) and various IR and NMR spectroscopic quantities is assessed through DFT calculations. Three different Lewis acids place a Br or I atom on a phenyl ring; each is paired with a collection of N ...

Dynamic Responses of Cylindrical Whispering Gallery Mode Revealed by Axial Liquid Disturbance
IEEE Photonics Journal, 2020 Cylindrical whispering gallery mode (WGM) microresonators have achieved much attention in the sensing field due to high sensitivity, compatibility and integration. The excitation of spiral modes in such a resonator is unavoidable, causing the axial field

Observation of Ultrashort Laser Pulse Evolution in a Silicon Photonic Crystal Waveguide
Micromachines, 2021 Using the sum frequency generation cross-correlation frequency-resolved optical gating (SFG-XFROG) measurement setup, we observed the soliton evolution of low energy pulse in an Si photonic crystal waveguide, and it exhibited the pulse broadening, blue ...
