Abstract
A miniature in-line fiber-optic Fabry-Perot etalon sensor is fabricated on a photonic-crystal-fiber (PCF) by using 157nm laser micromachining for the first time to our knowledge. Experimental results show that such a PCF-based etalon sensor has an excellent fringe visibility of up to ~26dB due to the mirror-finish quality of the two cavity surfaces inside the PCF. This etalon sensor can be used as an ideal one for precise strain measurement under high temperature of up to 800°C. It can offer other outstanding advantages, such as fast and easy fabrication, high reproducibility, capacity of mass-production, low-cost, low temperature-strain cross-sensitivity, and high signal-to-noise ratio, etc.
