Paper Abstract

We demonstrated a novel method for temperature-independent refractive index measurement by use of a Bragg grating fabricated in a highly birefringent rectangular microfiber. The two reflective peaks corresponding to two polarization axes exhibit almost identical temperature sensitivity of 12.01 pm/°C and different responses to ambient refractive index of 38.9 and 46nm/RIU at RI of 1.36, respectively. By monitoring the wavelength separation between the two peaks, temperature-independent refractive index measurement can be achieved.
