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<sup>-3</sup>. 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.
