Abstract

Highly birefringent (Hi-Bi) microfiber-based fiber loop mirrors (FLMs) are studied for gas pressure measurement. A elliptical microfiber is made by tapering a femtosecond laser-processed single mode fiber and demonstrated a very high birefringence of up to 10-2 . The microfiber is housed within a pressure tube with which gas pressure measurement is carried out. The robust microfiber sensor demonstrates a pressure sensitivity of 6 pm/kPa with a temperature cross-sensitivity of less than 0.01 nm/K.
