The State-of-the-art Electronic Photonic Design Automation (EPDA) Workflow

We will demonstrate the latest capabilities in the premiere electronic photonic design automation (EPDA) workflow offered by Cadence and Ansys Lumerical. This schematic-driven workflow offers electronic/photonic simulation using co-simulation or photonic Verilog-A, layout with Cadence CurvyCore technology, and custom component simulation using the direct bridge between Virtuoso Layout Suite and Ansys Lumerical multiphysics solvers. In addition, it enables parameter extraction and automated building of compact models for both PDK development and custom component design.

Co-packaged Photonics for Next-Gen AI/ML Systems

Tomorrow's AI and machine learning systems will need unprecedented bandwidth escape density to connect more processor cores to incoming data and memory. With copper interconnect reach at around 1m for the latest generation of data rates, optical interconnects play a critical role to enhances the bandwidth density and reach per power capabilities. These system can support large-scale topologies and dynamic bandwidth capabilities that can result in faster time to convergence for model training and overall system performance where reaction time is critical, such as autonomous vehicles. In this talk, I will highlight our recent efforts to enable a multi-generation of silicon photonics interconnects to serve our product portfolio.

Optical I/O solutions for Next-Generation Computing Systems

A slow-down in Moore’s law and increasingly data-heavy applications have pushed computing systems to larger, more interconnected architectures. The I/O requirements associated with these trends have driven the traditional I/O roadmap to its near end. Ayar labs’ technology addresses this I/O bottleneck with co-packaged optics which provides electro-optic conversion close to compute, enabling unprecedented bandwidth, latency and energy efficiency for chip-to-chip communication. In this talk, I will give an overview of this technology, and showcase the use of simulation and design tools to overcome challenges associated with introducing photonics on an electronic chip.

AIM Photonics Process Design Kit Enablement in Ansys Platform

In this presentation we discuss AIM Photonics PDKs developed in the Ansys/KLayout platform for photonic integrated circuit (PIC) design.

AIM Photonics has developed 300 mm silicon photonics technologies at the Albany Nanotech Complex, that target traditional applications such as data and telecommunications as well as emerging areas like sensors, 2.5D laser integration and quantum computing.

PDK features that enable efficient schematic and layout in these technologies are presented. AIM Photonics PDKs contain multiple INTERCONNECT Compact Model Libraries (CML) that are developed by domain experts. These CMLs contain hardware-validated component models that target a broad wavelength range as well as statistical models that capture the underlying process variations. Layout-schematic communication is enabled via the SiEPIC toolset and Lumerical-Klayout integration capability.

In addition to PIC design, tools that aid custom component design in AIM Photonics PDKs are also presented. In addition to process stack information included in our Design Manual, AIM Photonics offers a Lumerical Layer Builder process stack file that applies linewidth corrections and doping information to imported layouts increasing the accuracy of the component design.

Optimize & Accelerate Photonic Innovation

With the rise of cloud computing, companies can access seemingly limitless compute power at exponentially decreasing cost. This provides a fantastic opportunity to shorten design cycles and improve designs using photonic simulation tools. We will show how advanced optimization algorithms driving simulation tools on High Performance Computing (HPC) systems can yield improved designs, higher quality designs and deeper understanding. We will showcase examples of these techniques applicable to photonic integrated circuits, augmented reality glasses and displays.

Light Source Modeling with Ansys Lumerical

We will review the basic physics of light source generation in semiconductors, then explore how Ansys Lumerical tools can be used for LED and laser design. We will show how the various building blocks, such as multi-quantum well layers, waveguides, periodic reflectors and more can be designed, and then look at how full laser and microLED simulation can be performed. We’ll see how lasers for photonic integrated circuits can be simulated as compact models that drive an entire system. Finally, we’ll see how microLED and OLED simulation can be used in combination with Ansys Speos to study full displays and how they will be perceived by humans at different viewing angles and lighting conditions.

Fiber to Waveguide Coupling with Micro-optics

The increasing importance of fiber communication in 5G applications and more comes with many challenges in design and fabrication. One of the key challenges is the coupling between fiber and waveguide. Due to the size mismatch of the two devices, we need a robust method to couple light in between them with minimum loss. To design and simulate the coupling performance, Ansys developed the Lumerical + Zemax integration. With this integration, we can simulate light coupling in micro- to macro-scale, hence adjust the performance of the fiber-waveguide coupling. In this presentation, we will demonstrate the integration workflow and explain how it can help with the challenge mentioned above.

From Poisson to Maxwell: How Tower Modeling Team Creates Photonic Compact Models

This presentation shows the challenges faced by Tower modeling team when we are tasked with the delivery of photonic compact models. Physics of light and physics of electrons and holes are very different, optical signals have more state attributes (polarization, radiation) than electrical signals, modeling optical devices with analytical equations can be difficult, to name a few. The presentation also shows how Ansys Lumerical Compact Model Library Compiler (CMLC) enables us to accomplish our task. CMLC supports many optical models and templates that we can leverage, and has a specific data schema that accepts experimental data as well as simulated data. A step-by-step example will also be given on how the compact models for Tower PH18 directional couplers are created, and how they can be improved with various Ansys Lumerical workflows and Tower own process file.
