About This Webinar
From the moment of their initial introduction, metalenses have ignited the creative minds of engineers working in the realms of optics and photonics. LightTrans International’s team, the creators of the optics software VirtualLab Fusion, are dedicated to offering modeling and design tools that assist their clients in exploring the capabilities of metalenses in their respective applications. During this webinar, Frank Wyrowski shares strategies for the design and simulation of metalenses in common application contexts. He is eager to showcase cutting-edge advancements and discuss future plans for expanding these concepts in 2024. He aims to motivate the optics community to share their anticipations regarding the functionalities that an optics software should encompass for the utilization of metalenses.

Metalenses are a part of the flat lenses category, which also includes Fresnel and diffractive lenses. Hence, Wyrowski’s initial aim is to offer an overview of the concepts associated with the flattening of lenses. Following this, he delves into considerations such as the commonalities and distinctions that exist between a diffractive lens and a metalens, how each one is constructed and modeled, and what the process of replacing a smooth lens surface with a flat one entails. When developing optics software, striking an optimal balance between the simulation speed and precision is of paramount importance. Flat lenses have the same diameter as thick lenses, which are typically a few centimeters or millimeters long, with nanostructures spread over their surface. It is also anticipated that flat lenses will be employed with thick lenses in systems. This leads to a multi-scale setup that necessitates the use of highly sophisticated simulation methods to maintain a suitable balance between accuracy and speed. Wyrowski presents approaches to manage this situation.

Who should attend:
Engineers and R&D scientists in search of concepts and optics software that enable multi-scale simulations for systems with metalenses, which assist in evaluating and understanding the capabilities of metalenses for their specific uses.

About the presenter:
Professor Frank Wyrowski established LightTrans International in 1999, followed by the founding of Wyrowski Photonics in 2014, and later Beijing Luoxun Technology Co., Ltd. in 2022. His primary research goal is to enhance the accuracy and efficiency of optical modeling software, adhering to the principle of attaining necessary precision while optimizing speed. His strategy integrates various optical modeling techniques, ranging from geometrical to physical optics, into a unified simulation and design platform. This core concept underpins the VirtualLab technology, which is integrated into the VirtualLab Fusion software. The strategy of combining compatible modeling techniques on a single platform allows VirtualLab Fusion to address a wide range of multi-scale modeling and design challenges in contemporary optics and photonics, catering to a growing user base.
