Silicon Photonics Toolkit

Numerical simulations are essential for modeling and predicting the behavior of complex systems in many fields of research and development including applications in physics and material science, medical and biological sciences, environmental sciences, and many engineering disciplines [1-15]. The accuracy of simulation results in many of these examples depends on externally specified or separately simulated sets of parameters, which have critical implications for the outcome of the simulations. For example, many physical properties of materials play critical roles in shaping the performance of electro-optical and micro-electromechanical devices that underpin today’s modern computing and communications infrastructure [1-6]. Thermodynamic behavior and properties of chemical mixtures are instrumental in understanding and designing more efficient and cost-effective chemical processes [7-11]. The biomechanical properties of tissues, including their tensile and elastic properties, can have a direct impact on the design choices of numerous medical devices including implants [12-15]. As more devices and systems in virtually all areas of science and engineering are being designed and optimized by machine learning-based techniques today, efficient and rapid access to such application-specific parameters remains an important requirement in the future landscape of scientific design and modeling.

In integrated optics, accessing optical parameters of waveguides is one of the most important yet recurring tasks in the process of designing photonic devices. Silicon Photonics Toolkit (sipkit) is a python package that provides computationally efficient access to waveguide parameters as functions of key optical and physical variables, to aid the design of silicon photonic systems and scientific discovery through integrated optics. In addition to its state-of-the-art data mapping for rapid parameter access, sipkit also allows for full automatic-differentiation capability through its compatibility with JAX. With efficient gradient computation for optimization algorithms, sipkit can therefore be used in the design of photonic systems using modern machine learning methods. With this combination of streamlined data access and support for automatic differentiation, sipkit enables researchers and engineers to design complex photonic systems with greater efficiency and flexibility.

Getting Started

Silicon Photonics Toolkit is a toolkit providing fundamental waveguide and material properties to aid in the design of silicon photonic components on silicon-on-insulator platforms with high accuracy and extremely fast runtime. All the waveguide parameters returned by sipkit are calculated for 220-nm-thick strip waveguides on a SOI. See the documentation for tutorials and API reference.
