Abstract

An in-line fiber F-P sensor is formed by splicing a section of hollow-core photonic bandgap fibers in between two single mode fibers. Such a F-P sensor can be used under high temperature of up to 600 °C, and has a low temperature sensitivity of ~1.05nm/°C, while it has a relatively high strain sensitivity of ~5.93nm/με. Moreover, this F-P sensor is insensitive to bend or transverse load. Furthermore, the long cavity length (>1cm) of the sensor makes it suitable for multiplexing. These characteristics would make this F-P sensor to be an excellent strain gauge for use in high temperature environments.
