Abstract: | A novel polarization splitter based on photonic crystal fibers (PCFs) with three cores of high birefringence is proposed.
The 45° linearly polarized light is launched into a core. After a coupling length (about 1500 μm), the xand y-polarized light beams are separated into different cores. When the light is launched into another core, the xand y-polarized light from different cores can be obtained and the degree of separation can be also adjusted. The polarization
splitter is highly flexible and adjustable. The length of the polarization splitter is about 1500 μm which is just the coupling
length. So it has appreciate significance of manufacturing mini-type photonic apparatus in integrated optics. |
