Sensitivity collapse in whispering gallery mode refractometric sensing of porous microspheres: A finite-window mode-misassignment mechanism

Fluorescence-based whispering-gallery-mode (WGM) sensors routinely report refractometric sensitivities far below the intrinsic limit Sintrinsic = λ/neff, yet the origin of this discrepancy has not been rigorously quantified. Here we show that a…

Fourier-Transform-Based Metrology for Whispering Gallery Mode Spectra in Soft Photonic Microcavities

We present a Fourier-transform (FT)-based framework for quantitative analysis of whispering gallery mode (WGM) spectra in soft photonic microcavities. By treating the WGM spectrum as a quasi-periodic signal, the method enables robust extraction of…

Simulation of Rydberg Ionization in Atomic Beams for FIB Optimization

This study explores the excitation and ionization of an atomic beam as a pathway to optimize focused ion beams (FIBs) for high-precision applications. Leveraging the unique advantages of Rydberg excitation followed by field ionization-specifically…
