Abstract

We present a theoretical and experimental study of a tapered optical fiber-based sensor design that significantly increases optical detection sensitivities for measurement of small mechanical deflections in diaphragm-type fiber optic pressure sensors. By using tapered fibers, we experimentally observed up to eight-fold increases in optical signal modulation levels. We also discuss taper design considerations that maintain system optical power throughput and provide consistent increases in numerical apertures.
