Multiple mode band engineering in 1D grating-based photonic crystal waveguides for multidimensional silicon on-chip filters

Caption

Schematic of the proposed 1D grating-based photonic crystal waveguide (PCW) for multidimensional silicon on-chip filters. The structure employs a transverse-width-engineered z-periodic grating to expand the number of supported Bloch modes and their photonic bandgaps, enabling all-pass, selective-pass, and all-block regimes for broadband higher-order-mode manipulation.
