摘　　要：A multilayered configuration broad bandwidth polarization insensitive reflector realized by a multi-subpart profile grating structure is presented. The properties of the reflector are investigated by rigorous coupled-wave analysis. It is shown that over a broadband spectrum of 1.62-1.76μm, the reflector demonstrates high reflectivity （R 〉 99%）, low polarization-dependent loss （PDL〈 0.02 dB） and good angular insensitivity of about 29.6% for both transverse electric and transverse magnetic polarized waves.A multilayered configuration broad bandwidth polarization insensitive reflector realized by a multi-subpart profile grating structure is presented.
