Abstract
We report a novel type of highly birefringent suspended core (SC) photonic microcells made by selectively inflating four air-columns in a solid core photonic crystal fiber. The wavelength-scale SC has two-fold rotational symmetry and exhibits high phase and group birefringence of ~3 x10-3 and ~5 x10-3 respectively at 1550 nm. By incorporating such microcells into Sagnac fiber loop interferometers, we demonstrated refractive index, temperature and gas pressure sensors with good performances.
