Waveguide Geometry–Driven Trade‐Offs in Resonant Cavity Sensor Performance
Advanced Optical Materials, EarlyView.Waveguide geometry governs the interplay between sensitivity, intrinsic Q‐factor, and wavelength noise in silicon nitride resonant sensors. Contrary to intuition, higher sensitivity does not ensure superior performance. Low‐noise, high‐Q ridge resonators achieve the lowest detection limits, revealing that detection is ultimately constrained by noise ...
