CAD models for optical integrated circuits using the radiation spectrum method (RSM) with evanescent modes

Abstract

In this wok, we develop CAD models for optical integrated elements using the Radiation Spectrum Method with evanescent modes focusing on elements based on air gaps in semiconductor waveguides. The effect of the evanescent modes in the simulation and modeling is thus considered. For the simulation of photonic band gap optical integrated circuits, the developed models are introduced in a standard microwave simulator. Thus, the optical circuit can be simulated and its performance.
