Multi-layer photonics modeling framework for the design, analysis, and optimization of devices, links, and networks

摘要

Requirements on photonics modeling vary significantly when aiming to design, analyze and optimize a single device, a complete transmission link or a complex network. Depending on the task at hand, different levels of detail for emulating the underlying physical characteristics and signal interactions are necessary. We present a multi-layer photonics modeling framework that addresses the different design challenges of devices, links and networks. Our discussed methodology is based on flexible optical signal representations, equipment models ranging from very detailed to high-level parametric, sophisticated numerical algorithms and means for automated parameter and technology variation and optimization. We discuss applications such as the detailed modeling on photonics integrated circuit level, the characterization of a high-speed transmission link utilizing multilevel modulation and coherent detection, the parametric analysis of transmission links and network dynamics, and the cost-optimized placement of equipment in moderately complex networks.
