Abstract
We propose a compact ultra-broadband silicon-on-insulator polarization rotator. The conversion area of the polarizer rotator is a stair-shaped waveguide, where the middle step is partially replaced by a sub-wavelength grating. The length of the conversion region of the polarization rotator is only 3.36 µm. For TM-TE and TE-TM working cases, the insertion loss is less than 0.9 dB, the polarization conversion efficiency reached 99%, and the polarization extinction ratio is greater than 20 dB, in an ultra-broad wavelength range of 1260 nm to 1740 nm, which covers O-, E-, S-, C-, L-, and Ubands.
