Efficient Design of Photonic Integrated Circuits (PICs) by Combining Device- and Circuit- level Simulation Tools
نویسندگان
چکیده
This work addresses a versatile modeling of complex photonic integrated circuits (PICs). We introduce a cosimulation solution for combining the efficient modeling capabilities of a circuit-level simulator, based on analytical models of PIC sub-elements and frequency-dependent scattering matrix (S-matrix) description, and an accurate electromagnetic field simulator that implements the finite element method (FEM) for solving photonic structures with complicated geometries. This is exemplified with the model of a coupled-resonator induced transparency (CRIT), where resonator elements are first modeled in the field simulator. Afterwards, the whole structure is created at a circuit level and statistical analysis of tolerances is investigated.
