COMSOL Day: Optics & Photonics

See what is possible with multiphysics simulation

Join us for a full-day online event focusing on optics and photonics. You will have the opportunity to meet COMSOL technical staff and COMSOL users designing and analyzing optical devices and systems.

This event will feature a guest panel of industry users, presentations, and question-and-answer sessions covering a variety of topics within optics and photonics. The applications covered will span a wide range of length scales, from nano- and micro-optical devices to large-scale systems like cameras and telescopes. Specific examples include waveguides, lasers, scattering, photonic devices, optoelectronics, lighting, lidar systems, spectrometers, interferometers, solar radiation, and more. Novel engineering involving optics like metamaterials and plasmonics will also be presented, as will multiphysics combinations and simulation apps.

We welcome both experienced COMSOL Multiphysics® users and those who are new to the COMSOL® software to attend. Feel free to invite your colleagues. View the schedule below and register for free today!


11:00 a.m.

To start, we will briefly discuss the format of the day and go over the logistics for using GoToWebinar.

Trends in Optics and Photonics Simulations

An overview of current challenges in simulating optics and photonics will start this COMSOL Day. This includes applying numerical modeling to systems ranging from the subwavelength scale to optically large systems. Robust modeling of these phenomena leads to better design and optimization of applications dependent on optical wave communication; media conductive to guiding photonic, microwave, and nanowave electromagnetic radiation; plasmonic materials and metamaterials; devices used in optical sensing and imaging; applications dependent on laser-material interaction; energy conversion through photonic means; and lighting.

Tech Café: Building Simulation Apps for the Optics Industry

Simulation applications enable you to expand the power of modeling by providing control over design and optimization decisions to colleagues who require simulations for such tasks. You can create user-specific modeling user interfaces and platforms best suited to your colleagues' simulation needs while also integrating ease of use into apps, making them applicable for traditionally nonmodeling engineers.

During this Tech Café, you will be able to discuss how best to develop simulation apps together with COMSOL engineers and other colleagues from industry. A selection of simulation applications from the field of wave and ray optics, including fiber optics, plasmonic wire gratings, a solar dish receiver designer, and a Si solar cell that combines the simulation of ray optics with semiconductor physics, will be available to be demonstrated and discussed on demand.

Parallell Session
Wave Optics Simulations in a Multiphysics Context

In this session, we will present an overview of the Wave Optics Module, especially when subject to other physics phenomena. This module solves the Maxwell equations to simulate an optical wave’s propagations, reflections, refractions, absorptions, scatterings, diffractions, and other optical phenomena in space dimensions that are similar in size or larger than the propagating wavelength. Typical applications are waveguides, gratings, photonic crystals, nanoantennas, resonators, lenses, couplers, modulators, filters, holograms, and optical fibers. In particular, we will cover wave optics multiphysics effects such as electro-optical, stress-optical, and semiconductor-optoelectronic couplings.

Tech Café: STOP Analysis

Modern optical systems are often required to operate in harsh environments, including high altitudes, space, underwater, and in laser and nuclear facilities. Such optical systems are subjected to structural loads and extreme temperatures. The most accurate way to fully capture these environmental effects is through numerical simulation via a structural-thermal-optical performance (STOP) analysis. STOP analysis is the quintessential multiphysics problem and will be discussed during this Tech Café. You will be able to share your experiences and ask questions of COMSOL engineers responsible for the implementation of features used to model such phenomena.

Parallell Session
Ray Optics Simulations in a Multiphysics Context

This session will focus on modeling multiphysics phenomena using the Ray Optics Module, typically for systems encompassing reflection, refraction, or absorption phenomena where the geometry is large in comparison to the propagating wavelength. This module is used to model many applications, including lenses; cameras; interferometers; telescopes; monochromators and spectrometers; solar radiation and energy harvesting; laser focusing systems; cavity stability; graded index media; and lighting systems for rooms, buildings, and the automotive sector. We will explore modeling multiphysics phenomena based on ray tracing, such as in ray heat sources, and the effects of temperature gradients and deformed geometries on wave propagation. This is best simulated through the application of high-fidelity structural-thermal-optical performance (STOP) analysis.

Tech Café: Simulating Quantum-Optical Devices and Semiconductor-Optical Systems

Quantum effects are becoming increasingly exploited in technical applications such as computing processes, optical sensors, photonic-based communication media, and security systems. They are prevalent in applications such as the determination of photovoltaic cell efficiency and even the color of light-emitting diodes (LEDs). In this Tech Café, we will explore the interaction between electronic and optic phenomena down to the level of single photons. The Schrödinger Equation interface in the Semiconductor Module will be an integral part of this Tech Café, as it allows users to model quantum-confined systems such as quantum wells, wires, and dots. In addition, optical transitions can also be incorporated into this interface to simulate a range of devices, such as solar cells, LEDs, and photodiodes.

3:15 p.m.
3:30 p.m.
Parallell Session
Thermal Modeling of Lasers in Manufacturing Processes

The modeling of space- and time-varying heat application and transfer in manufacturing processes by using lasers will be covered during this session. This involves the manipulation of source terms in the specification of boundary and volumetric domain conditions through solving, among others, the Beer–Lambert law. The modeling of complicated motion paths will also be covered.

Applications of these demonstrated modeling techniques are useful for modeling laser heating processes, and can also be extended to include the modeling of ablation, phase change, and melt-pool simulations. Together, these can be applied to simulating medical and aesthetics treatment, noninvasive cancer surgery, welding, annealing, semiconductor processing, material polishing and microshaping, selective laser melting, and sintering.

Tech Café: Simulating Illumination and Lighting Systems

In this Tech Café, you will be able to discuss how best to model light sources, such as sunlight and LEDs, in applications such as rooms, buildings, and small enclosed spaces like automobile cabins. Along with fellow colleagues and COMSOL technical staff, we will discuss how the reflection of light from building surfaces, the propagation of light in pipes and tubes, and other applications can be simulated through manipulating the import of light source data from, e.g., IES files, the superposition of light sources, and the calculation photometric quantities.
