Next-generation 6G optical networks demand compact, low-Size, Weight, Power & Cost (SWaP-C) units that split and switch ultra-wideband spectra. We developed a general synthesis and experimental validation of two-port multi-tap interferometric optical filters—realized as cascaded Mach–Zehnder delay-line stages on a PIC photonic chip, with each tap comprising a 50:50 directional coupler, a programmable phase shifter, and a discrete time-delay element. This algorithm maps any real-coefficient FIR response into discrete optical delays and programmable tap weights. Using an ASE broadband source and an optical spectrum analyzer, our goal is to demonstrate low insertion loss and >-23 dB stop-band attenuation —even under noisy conditions—confirming the filter’s suitability for ultra-wideband 6G applications.
