Polymer Microbubble-Based Fabry–Perot Fiber Interferometer and Sensing Applications
TL;DR: In this article, a polymer microbubble-based Fabry-Perot fiber interferometer (FPI) for pressure and temperature measurement is proposed and demonstrated by splicing a small segment of photonic bandgap fiber to a singlemode fiber and immersing such a fiber tip into an optical adhesive, a micro air bubble could be buried into the formed polymer diaphragm.
