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.

Design Tools for Next-Generation Silicon Nitride Photonics

In this presentation we will review the design flow and design tools to optimize photonic designs that work right the first time, considering process variations.

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.

The Alcyon library of Photonics Blocks and its Environment for PIC Design

Alcyon Photonics will present how its design environment allows to interact smoothly with its library of validated photonics blocks, combine together with foundry and user designs to build photonics circuits. This environment significantly facilitates users' photonic chip design work and, it is freely available under registration and is compatible with Ansys-Lumerical. 

Learn more on how Alcyon leverages its know-how design to deliver a portfolio of combinable photonics designs through an open innovation environment, soon available for fabrication at Applied Nanotools.
