摘　　要：In this paper, a binary blazed grating-based polarization independent filter on silicon on insulator （SOI） under full conical incidence is presented. The properties of the grating filter are investigated by rigorous coupled-wave analysis. It＇s shown that the filter demonstrates high reflectivity （R 〉 99%） at its resonant wavelength, which stays the same under three different polarization states. It indicates that this grating filter is polarization-independent. The final data shows its polarization-dependent loss （PDL） is only 0.04 dB and the full width at half maximums （FWHMs） of the transverse electric （TE-） and transverse magnetic （TM-） polarized light are 0.24 and 0.46nm, respectively.In this paper, a binary blazed grating-based polarization independent filter on silicon on insulator （SOI） under full conical incidence is presented.
