A High-Order Lattice Filter with Enhanced Passband and Roll-off for CWDM4 Applications

Abstract A silicon nitride high order lattice filter with a flat-top response is demonstrated for CWDM4 applications, exhibiting 1 dB insertion loss, a 17.9 nm 1dB bandwidth, and a sharp roll-off of 81% in BW 1dB / BW 10dB .
