Abstract

We present an optical fiber ferrule-top sensor for humidity measurements. Changes in water content in a gaseous environment are detected by monitoring the resonant frequency and the quality factor of a cantilever fabricated on top of a ferruled optical fiber. Our experimental data demonstrate that the device offers high resolution and high repeatability.
