Abstract

We present a new design for simultaneous strain and temperature discrimination using a high-birefringence fiber loop mirror (HiBi-FLM) concatenated with a temperature insensitive long-period grating (LPG) written in a photonic crystal fiber (PCF). The FLM acts as a sensor head, while the LPG in PCF serves as a filter to convert wavelength variation to optical power change. By measuring the wavelength variation and the power difference of two near peaks in the spectral response of this configuration, strain and temperature discrimination is obtained.
