Abstract:

Silica capillary is widely used in optical fiber sensors with different structures and functions since its material has the same inherent property as fibers. This paper first introduce mode distributions and splicing process of the fiber and capillary. The recent advances in optical fiber sensors based on interference-type capillary are present, mainly with the Fabry-Perot type, multimode interference type and anti-resonance type. The recent advances in optical fiber sensors based on capillary combined with microcavities are then introduced, including the multimode fiber based sphere microcavity, and the microcavity based on cone-shaped in-wall capillary. Finally, we introduce the recent advances of optical fiber sensors based on capillary in the area of optofluidic, because of the center empty channel inside the capillary and the cylinder structure to suppport the whispering gallery mode.

Key words: microcavity, optofluidic, capillary, optical fiber sensor, interference type optical fiber sensor
