This paper presents a novel wideband baseband macromodeling framework tailored for the representation of linear and passive photonic filters. The proposed framework is able to efficiently estimate the baseband scattering representations of such filters as a function of the delay in the waveguides that control their center frequency. Notably, the macromodel allows for frequency and time-domain simulations at arbitrary optical carrier frequencies, making it especially well-suited for multi-wavelength system modeling and simulations. Although initially demonstrated in the context of photonic filters, a similar approach can be applied to baseband radio frequency (RF) systems. One application example is presented to demonstrate the flexibility and advantages of the proposed method.
