Abstract
The modal and group birefringence of a hybrid photonic crsystal fiber (Hybird-PCF) and their responses to strain and temperature are studied theoretically and experimentally. The birefringence properties of a section of Hybrid-PCF manufactured by University of Bath were measured by using a Sagnac interferometer. The group birefringence, strain and temperature responsivities of modal birefringence of this Hybrid-PCF were measured to be ∼2.5*10-4, 4.39*10-4 (ε-1) and -1.05*10-7 (°C-1) respectively. The birefringence properties of Hybrid-PCF can be adjusted by changing the molar concentration and diameter of its Ge-doped regions.
