“…PicWAVE uses a time-domain travelling wave (TDTW) optical model [6], and RSoft Optsim uses SSM [7]. There are also approaches that use Modified Node Analysis (MNA), such as OptiSPICE [8,9], which allows simulation of mixed electronical and optical circuits. All of these new tools will become indispensible in the future when designing and optimizing large optical circuits.…”

We present a tool that aids in the modeling of optical circuits, both in the frequency and in the time domain. The tool is based on the definition of a node, which can have both an instantaneous input-output relation, as well as different state variables (e.g. temperature and carrier density) and differential equations for these states. Furthermore, each node has access to part of its input history, allowing the creation of delay lines or digital filters. Additionally, a node can contain sub-nodes, allowing the creation of hierarchical networks. This tool can be used in numerous applications such as frequency-domain analysis of optical ring filters, time-domain analysis of optical amplifiers, microdisks and microcavities. Although we mainly use this tool to model optical circuits, it can also be used to model other classes of dynamical systems, such as electrical circuits and neural networks.

“…Note that the current level of integration has been reached by micro-electronics by 1969 -during the infancy of the first electronic circuit analysis programs [3]. Remarkably, now we recapture those times once again, living in the beginnings of commercially available photonic circuit simulators [4][5][6][7][8][9].…”

We present our approach towards an automated design framework for integrated photonics and optoelectronics, based on the experience of developing VPIcomponentMaker Photonic Circuits. We show that design tasks imposed by large-scale integrated photonics require introducing new "functional" types of model parameters and extending the hierarchical design approach with advanced parameter scripting capabilities. We discuss the requirements imposed by the need for seamless integration between circuit-level and device-level simulators, and illustrate our approach for the combination of VPIcomponentMaker Photonic Circuits and VPImodeDesigner. We show that accurate and scalable circuit-level modeling of large-scale photonic integrated circuits requires combination of several frequency-and time-domain simulation techniques (scattering-matrix assembly, transmission-line models, FIR and IIR digital filters, etc) within the same circuit simulation. We extend the scattering-matrix assembly approach for modeling linear electronic circuits, and motivate it being a viable alternative to the traditional modified nodal analysis approach employed in SPICE-like electronic circuit simulators. Further, we present our approach to support process design kits (PDK) for generic foundries of integrated photonics. It is based on the PDAFlow API which is designed to link different photonic simulation and design automation tools. In particular, it allows design and optimization of photonic circuits for a selected foundry with VPIcomponentMaker Photonic Circuits, and their subsequent export to PhoeniX OptoDesigner for layout verification and GDSII mask generation.

“…A different approach is to use the Modified Nodal Analysis (MNA), as used in electronic simulation tools, and extend this to the optical domain by mapping power, wavelength and phase onto voltages and currents, see e.g. [4,5].…”
