IPR Debate - Integrated Photonics: What Didn't Work Quite as Expected

Take a break from IPR bleeding-edge research with a session welcoming a reflection on the path that brought photonics to where it is now. Three distinguished panellists will share their view on well-established research topics that have not lived up yet to expectations. Join and defend your beloved study or support our speakers’ view.

Format: Each panellist will present their view on the selected topic listed below (~15m), followed by a discussion (~15m) between the panel and the public.

Panelists include:
Roel Baets, Ghent University, INTEC, Belgium
Light Sources on Silicon: Nothing Beats III-V

Jacob Khurgin, Johns Hopkins University, USA
Why LiNBO3 is Still the King of Modulators?

Thomas Krauss, University of York, UK

Symposium: Bioinspired Optics: From Fundamental Biology to Tools and Applications

The thematic focus of this symposium will be on the interdisciplinary area of bioinspired optics: specifically, understanding nature’s optical design principles and leveraging them for the development of novel optical tools. The talks will cover various approaches in biomolecular engineering and nanofabrication methodologies, which strive to emulate some of the unique light-manipulating capabilities of living systems, as well as the implementation of new optical characterization strategies. The symposium aims to encourage interdisciplinary discussion, with the simultaneous hope of identifying new research opportunities in bioinspired optics and photonics, advancing fundamental biological understanding, and accelerating next-generation optical tool development. Through our cross-disciplinary focus, we are striving to cultivate a cohesive and inclusive community of scientists at all career stages and from across all demographic groups.

Symposium: Forty Years of Light Management

Forty years ago, in December 1981, Eli Yablonovitch submitted his seminal paper on “Statistical Ray Optics,” which was one of the first papers investigating light management for solar cells from a fundamental physics perspective.

Light management has mainly been performed with antireflective coatings and textures, which enhance the average light path and hence, absorption in the solar cells. In the last twenty years highly innovative concepts were also investigated, such as (quasi)periodic structures, plasmonic nanostructures, Bragg reflectors, and photonic up- and downconversion. On the other hand, state-of-the-art silicon solar cells have almost perfect light trapping with external quantum efficiencies close to 100% for a broad wavelength range using only conventional light trapping techniques.

With this symposium, we aim to bring together leading experts in the field representing all the light management concepts investigated during the past forty years. We will critically review different light trapping techniques developed in the past decades and discuss, how the field may and should develop further.
