Abstract:

Optical fiber sensors based on Fabry-Perot interferometer (FPI) with an infiber air bubble have attracted much attention for sensing applications in gas-pressure and tensile-strain measurement. Based on the recent research progress, a new technique is presented, which can create an air-bubble-based FPI by means of improved electrical arc discharge. Only a common fusion splicer is needed without any additional equipment. In this paper, the FPI sensor with air bubbles is described. The fabrication method, principle of operation and sensing applications are discussed. Furthermore, a novel optical microresonator based on an in-fiber rectangular air bubble is demonstrated. Whispering-gallery modes can be tuned by applying tensile strain to the rectangular air bubbles.

Key words: air bubble cavity, gas pressure sensing, Fabry-Perot interferometer, optical fiber sensor, whispering gallery mode resonator, tensile strain sensing
