The proposed PRS is based on the 220 nm silicon- on-insulator platform, and it shows less than 0.27 dB insertion losses and larger than 14 dB polarization extinction ratios over a wavelength range from 1200 to 1700 nm. To the best of our knowledge, the PRS working in th~ whale nntie^l enmmunien,tinn hand is nrnnased far the first time.展开更多
