TRAIN YOUR DESIGN SKILLS WiTH VirtualLab Fusion
Introduction
The demand for physical optics simulation technology has grown distinctly to the point where, for many applications in modern optics, it simply cannot be avoided. Switching to a physical optics model only in those parts of the system where ray tracing is not expected to be an accurate option risks missing important information about the system, mainly due to the mutually incompatible mathematical models – rays and electromagnetic fields.
Furthermore physical-optical effects may also be relevant in other parts of the system were they were in principle not expected. This is the justification behind the proposal for a ›fast physical optics‹ approach: a physical optics technique which includes a generalization of ray tracing fully embedded inside the overarching physical optics framework, and which, consequently, provides physical optics simulation results just as fast as ray tracing.
In the OptoNet Summer Course Fast Physical Optics Modeling and Design, we will equip you with the necessary theoretical and practical knowledge to make the most of your work with the fast physical optics software VirtualLab Fusion!
PROGRAM & TRAINING CONCEPT
Physical optics simulation tools & technology are a must-have for the analysis and design of modern systems. In this course we will be employing the commercial fast physical optics modeling and design software VirtualLab Fusion to investigate a series of optical systems taken from a broad range of fields of application. We will use these examples to introduce the most important features and details of the underlying technology of the software, from a very general perspective in the first two introductory days, and with a focus on gratings as just one part of larger, more complex optical systems in the advanced course covering the last three days.
Some of the topics you can expect to hear about: interferometry, lens systems, anisotropy, fiber coupling, ultrashort pulses, meta gratings, augmented and mixed reality lightguides, and more!
lECTURERS
The course will be taught by experts of the Optical Engineering team at LightTrans. Their daily work in direct contact with users of VirtualLab Fusion from all over the world means that they do not only have in-depth knowledge of the software and how it works, but also, crucially, of how best to put it to use in order to satisfy the requirements of a wide range of nowadays demanded fields of application.
As a special highlight, the President and internationally renowned expert Prof. Dr. Frank Wyrowski (Friedrich-Schiller-University Jena) will give an introduction to the topic and current developments in the field of fast physical optics on the first day of the training.
The Introduction Parts from 04. – 05.07.2022 will be held by:
Senior Optical Engineer Hartwig Crailsheim and Optical Engineer Sohrab Sangini.
The Gratings Parts from 06. – 08.07.2022 will be presented by:
Principal Scientist Dr. Stefan Steiner and Senior Optical Engineer Olga Baladron-Zorita.
PARTICIPATION REQUIREMENTS & Modules
This course is designed for optical scientists, engineers, designers with varying levels of expertise with VirtualLab Fusion in mind, starting from total beginners.
- Introduction: This two-day course provides an overview of VirtualLab Fusion’s fast physical optics usage and technology, and shows how to apply said technology to a series of examples from a varied range of applications. Beginner to intermediate level.
- Gratings: This more advanced three-day course focuses on gratings, starting with the many tools available in VirtualLab Fusion to configure very different types of gratings as well as characterize and optimize gratings as standalone components (including metagratings); we then move on to include those gratings in more complex systems, where the gratings will be accompanied by other optical components. In the following part, as a notable application example, we devote some time to the modeling and design of lightguide devices with grating couplers for augmented and mixed reality applications. Advanced level.
- Both: The content of the courses has been designed so that it is possible to register for either of them separately, or to book both of them together.
VENUE
The Summer Course will take place in Jena, the city of Ernst Abbe and Carl Zeiss who laid the foundation for modern optics 150 years ago. Since then the science city Jena has been shaped by innovative, light-based technologies. Enjoy the spirit in the young university town surrounded by a magnificent landscape and well-known sights of European history.
The venue is the SCALA Panoramabankett Jena
The seminar will take place in the panorama banquet of the JenTower (27th floor), Leutragraben 1 in Jena. With professional technical equipment and a pleasantly undisturbed environment at a height of 128 m, the best conditions for concentrated work are created. During breaks, we offer healthy, balanced cuisine for refreshment and well-being.
