Paper Abstract

We present a theoretical analysis of the total collectible optical power of an arbitrarily shaped multimode optical fiber probe for contact sensing where the signal from the analyte is emitted or scattered on the outside surface of the fiber tip. Calculation results and optimization parameters are given for spherical, parabolic, and cone-shaped fiber probes. This analysis can be used to guide the design and optimization of various fiber sensors, including fluorescence, surface plasmon resonance, and surface enhanced Raman sensors.
