Abstract :
A novel kind of elliptical-hole highly birefringent microstructure optical fibers (MOFs) with two defects and six rings is analyzed and proposed. Simulation results show that geometrical birefringence of this elliptical-hole MOF is two times higher than that of the circular-hole ones, which found to be about 3.5×10-3. The polarization beat length of such fiber is calculated to be 0.44 mm. Besides, this kind of MOF with two defects can couple with single mode fibers efficiently and the confinement loss is almost near zero when the cladding ring number reaches 6. Such proposed fiber with high birefringence and low confinement loss can find really potential applications in the fields of light transmission and optical sensing.
