Abstract
We propose a simple procedure to design a structure that integrates spectral and polarization filters on a single chip. A simulation using rigorous coupled wave anlysis shows that structural adjustment based on the effective medium theory can achieve the desired integration without notable performance degradation. Our spectro-polarimetric filter design maintains spectral filter characteristics, while its extinction ratio is significantly enhanced over the passband. Based on the proposed spectro-polarimetric filter, we plan to build multispectral multipolarimetric filters for remote sensing applications such as to improve forest resource management.
