摘要

As the polarization state of laser can reflect more information, various types of laser remote sensing techniques have been developed. In order to accurately interpret the detection information, the optical components with polarization insensitivity has become an important topic. In this paper, a polarization insensitive splitter with three all-dielectric materials is designed and fabricated, which combines the symmetric structure with the matching layers. Statistical results show that this design has excellent performance of low polarization deviation at short wave region 420–580 nm with high reflectance and long wave region 620–880 nm with high transmittance.
