We report the fabrication of in-line photonic microcells (PMCs) by encapsulating tapered highly birefringent microfibers (Hi-Bi MFs) inside glass tubes. The encapsulation isolates Hi-Bi MFs from external environment and makes them more suitable for real-world applications. Gas sensing is realized by fabricating micro-channel on the PMC for ingress/egress. A fiber Sagnac loop interferometer (SLI) incorporating a Hi-Bi microfiber PMC demonstrated a gas pressure sensitivity of 599 pm/bar, and RI sensitivity of 2024 nm per refractive index unit (nm/RIU) in gaseous environment.
