Characterization, modeling, and design methodologies for integrated photonic components and circuits - verkefni lokið

Fréttatilkynning verkefnisstjóra


The main objectives of the project was development of surrogate models for integrated photonic components based on coarse-discretization EM simulations, investigating a possibility of utilizing 2D simulations to develop fast replacement models of 3D components, development of surrogate-assisted algorithms for reduced-cost design optimization of photonic components and devices, as well as numerical verifications of the developed methodologies by means of handling specific design problems. 

In the course of the project, several methodologies have been developed and implemented, all involving surrogate-based techniques and variable-fidelity EM simulations. The most interesting techniques include feature-based optimization framework, as well as geometry optimization based on iterative control of the problem dimensionality by using appropriate geometry parameterization techniques (e.g., splines) with variable number of control points.

Computer implementation of the numerical methods developed under the project has been carried out in Matlab and tested using specific design cases involving integrated photonic components such as add-drop filters, microring resonators, directional couplers, power dividers, and junction structures. The general conclusion of the project is that a right combination of physics-based low-fidelity modelling, model management, model correction, and iterative correction-prediction schemes, may allow handling expensive EM-simulation models of integrated photonic components in a computationally feasible manner, and, in some cases, lead to dramatic reduction of the computational cost of the design optimization process as compared to direct optimization of high-fidelity electromagnetic models of the respective structures. The results of the project should be of interest for engineers and designers dealing with microwave photonics but also related areas where utilization of electromagnetic simulation tools is widespread (microwave engineering, antenna engineering). Furthermore, we believe that the results will be of interest to other areas where the design is based on CPU-intensive numerical models such as structural and aerospace engineering, heat transfer, as well as automotive industry. The project resulted in a large number of publications, including 15 journal papers (all ISI-ranked) and 17 peer-reviewed conference publications.
