Design and Optimization of Broadband Optical Half-Band Filters Based on Cascaded MZIs

In optical communication systems, optical half-band filters are essential for efficient spectral separation, necessitating stringent performance criteria such as a wide spectral range, low insertion loss, and minimal crosstalk. This paper proposes a broadband optical half-band filter based on a casc...
