Abstract :
A photonic crystal fiber polarization rotator (PR) is proposed based on a novel mechanism-mode interference by two hybrid waveguide modes, rather than adjusting optical property in the light-guided part. The proposed PR is achieved by introducing two defects and an ancillary Au nanowire into the background lattice, and under the optimized parameters, the PR can offer almost a 100% polarization conversion ratio in the wavelength of 1.55-μm band (~100-nm bandwidth), compact length ~162.7 μm, low modal insertion loss of ~1.2 dB, and high coupling efficiency over 0.92 for both TE and TM mode based on the numerical simulation result of the full-vector finite-element method.
