Microbubble-Based Fiber Optofluidic Interferometer for Sensing

A fiber optofluidic interferometer based on an optical microbubble-on-tip (μBoT) structure is developed. The generation process and sensing mechanism of this μBoT sensor are very different from traditional optical fiber sensors. The μBoT is a hybrid solid/liquid/gas microstructure generated by heating a fiber tip with laser and can be easily regenerated with low cost and good repeatability. Carbon...
