A Novel Fiber Polarization Splitter Based on Orthogonal Dual Core
A novel polarization splitter is proposed in a photonic crystal fiber with orthogonal dual core. The device is designed by using index matching coupling theory. The proposed splitter exhibits some features, which has short splitting length (the minimum splitting length is 0.3 cm), low loss (the silicon fiber has been widely used in optical fiber communication) and so on. Moreover, it is easy to fabricate over its counterparts because the right core is equivalent to the left core rotated by 90°. It is extremely useful for the future applications of the broadband polarization device.
