“…Unfortunately, at this point there is only limited interoperability between tools of different vendors, even though some collaboration and standardization activities are emerging [197]. This also extends to integration of photonic design tools and electronics design automation (EDA) tools, as we see EDA vendors gradually supporting photonic design [198], [199].…”

Silicon Photonics is widely acknowledged as a gamechanging technology, driven by the needs of datacom and telecom. Silicon Photonics builds on highly capital-intensive manufacturing infrastructure, and mature open-access silicon photonics platforms are translating the technology from research fabs to industrial manufacturing levels. To meet the current market demands for silicon photonics manufacturing, a variety of openaccess platforms is offered by CMOS pilot lines, R&D institutes and commercial foundries. This paper presents an overview of existing and upcoming commercial and non-commercial openaccess silicon photonics technology platforms. We also discuss the diversity in these open-access platforms and their key differentiators.

“…Since photonic circuits and electronic circuits closely work together and are integrated, the simulation should be conducted in both domains. There are several simulation approaches to combine these domains discussed and implemented in both academia and industry [36]: simulate photonic circuits and electronic circuits in 1) photonic simulators; 2) electronic simulators; 3) separate electronic and photonic simulators with unidirectional data exchange; 4) separate electronic and photonic simulators with bidirectional data exchange (Co-simulation) [90]. Therefore, before building the model, we should also be aware of where the models will be evaluated: in a photonic simulator or an electronic simulator?…”

“…Among the four simulation approaches, the second option (adopting electronic simulators for both electronic and photonic circuits) has shown a lot of promise [91], [92]. It is important to note that optoelectronic devices such as detectors, amplifiers, lasers, and modulators can have both electrical and optical behaviors, and therefore must be simulated in both domains, especially if they have electrical control loops [36], [90]- [92], which indicates that it is better to simulate electrical and optical behaviors at the same time.…”

“…Bidirectional co-simulation is not trivial to implement and requires two simulators to operate in lockstep [90]. While such techniques are also used in analog-digital mixed-signal (AMS) design, it can raise questions about stability and conservation of energy when exchanging information between the two domain [89].…”

A foundry-based photonic ecosystem is expected to become necessary with increasing demand and adoption of photonics for commercial products. To make foundry-enabled photonics a real success, the photonic circuit design flow should adopt known concepts from analog and mixed signal electronics. Based on the similarities and differences between the existing photonic and the standardized electronics design flow, we project the needs and evolution of the photonic design flow, such as schematic driven design, accurate behavioral models, and yield prediction in the presence of fabrication variability.

“…In many cases, the number of wires in the bus is furthermore multiplied by the number of modes/polarizations in the waveguide (TE/TM) and the number of wavelength channels. This large number of wires in a bus makes the equivalent circuit models less compact and, as a result, the routing of large systems in schematics can become more confusing [18].…”

Passive photonic integrated circuits (PICs) can be easily characterized in the frequency-domain, but their accurate time-domain performance evaluation is a hurdle for systemlevel designers, especially when dealing with resonant circuits having highly dispersive behavior, such as ring resonators. In this paper, a new equivalent circuit modeling and simulation approach is proposed, based on the Complex Vector Fitting algorithm, able to perform accurate and robust time-domain simulations of passive PICs directly in standard SPICE simulators. The proposed modeling technique starts from scattering parameters of passive PICs, and is able to capture linear and high order dispersion, backscattering, and wavelength dependent effects. Considering the different nature of optical and electronic signals, a novel concept of equivalent voltage and current for optical waveguides is proposed to simplify the optical to electronic ports conversion and to make it possible to connect and terminate the equivalent circuit models as needed in SPICE simulators, natively supporting bidirectional signal propagation in a waveguide. This work provides a precise and reliable solution to evaluate timedomain characteristics of passive PICs and to access any internal nodes within a circuit, such as the signals inside a ring resonator. Three examples of time-domain simulations of passive PICs in commercial SPICE simulators are presented to demonstrate the flexibility and advantages of the proposed technique.
