Toralf Scharf received a MS degree from the University of Duisburg on surface physics in 1993 and a PhD in physical chemistry from the University of Halle, Germany when he work at the Max Plack Research group "Liquid crystalline systems" with A. Saupe. Since 1997 he has been a senior scientist at the Institute of Microtechnology in Neuchâtel. His scientific interests include electro-optic effects of micro-structured liquid crystals devices and combinations of micro - nanostructures in polymers to realize advanced optical systems. He has recently authored a book entitled Polarized light in Polymers and Liquid crystals published with Wiley.
He was nominated as InnoLecture Guest-Docent at the Ernst Abbe School of Photonics in Jena for the academic year 2011/2012 by the Carl Zeiss Foundation.
Toralf Scharf has received the Credit Suisse Award for Best Teaching, which goes to the best EPFL teacher in 2016.
Toralf SCHARF is coordinator of the Europeen project NOLOSS.
The target of this project is to prepare and train future engineers for the design challenges and opportunities provided by modern optics technology. Such challenges include lossless photon management, modelling at the system, components and feature level, and the link between design and technology. Today all optical designs are often perceived following different approaches, namely geometrical optics, physical optics and nano-photonics. Traditionally these approaches are linked to the different lengths-scale that are important to the system.
Starting from the entire system that is macroscopic and uses geometrical optics, over the miniaturized unit that is based on micro-optics and needs physical optics design, down to the active nano-photonics entity that allows steering light truly at the nano-scale but which requires to be designed with rigorous methods that provide full wave solutions to the governing Maxwell’s equations.
A design for manufacture of next generation optical applications necessarily requires to bridge the gap between the different length scales and to consider the design at a holistic level. At the core are optical simulation models developed and used in the academic research and the one used for optical designs in industry.
Up to now, only the academic partners apply an integral approach to include micro- and nano-photonics in their simulations. Together with the industrial partners projects will be launched to promote the academic developments in optical design and simulation over different length scales towards the industry. The industry will use the know-how to consolidate their expertise, expand their businesses, and occupy new fields of activities. For each research subject, may it be nano-photonics, micro-optics or system engineering, a channel can be provided to access particular knowledge and/or stimulate collaborations.
Toralf SCHARF was coordinator of the Europeen project NANOGOLD.
The NANOGOLD project aimed at the fabrication and application of bulk electro-magnetic metamaterials. We will apply self-organization of organic-inorganic composite materials containing resonant entities. To tune and optimize electromagnetic properties, resonance and interference at different length scales will be implemented. In such a way we will obtain bulk optical metamaterials with unprecedented properties operating in spectral domains appropriate for photonics that can be used in applications. Proof of principle devices will be the outcome of the project.
