Boxlike filter response based on complementary photonic bandgaps in two-dimensional microresonator arrays

摘要

We propose that a boxlike filter response can be obtained by utilizing complementary photonic bandgap properties of the column and row configurations in two-dimensional microresonator arrays. The filters are fabricated using deep-UV lithography in silicon-on-insulator technology. The observed sidelobes reduction is approx10 dB, and the usable bandwidth can be as high as 500-750 GHz.
