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 the optical path length <inline-formula><math xmlns=...
