英文摘要	a broadband polarizing beam splitter (pbs) with metal-wire nanograting in near infrared region is designed and analyzed. the grating profiles are optimized by use of rigorous coupled-wave analysis (rcwa) and the simulated annealing (sa) algorithm. based on the optimized structure, high polarization efficiency, high extinction ratio and large angular tolerance with a broad wavelength range (1-3 mu m) are obtained. both of the transmission efficiencies of tm-polarization and reflection efficiencies of te-polarization are over 95%. the extinction ratio of transmittance and reflectance are over 25 db and 16 db in the 1-3 mu m wavelength range, respectively. at the same time, as a comparison we also design a pbs with double-groove metal-wire nanograting, the grating has two grooves per period, which is different from conventional gratings. the pbs also has large angular tolerance, which is -40 degrees to 40 degrees. the designed grating can be used in optical communication and infrared imaging polarimetry.
