WEB Novel Photonic Architectures by Nanoimprinting Unconventional Materials

Tuesday (22.09.2020)
11:20 - 11:50 P: Processing and Synthesis 1
Part of:


Nanostructured dielectric and metallic photonic architectures can concentrate the electric field through resonances, increase the light optical path by strong diffraction and exhibit many other interesting optical phenomena that cannot be achieved with traditional lenses and mirrors. The use of these structures within actual devices will be most beneficial for enhanced light absorption solar cells, photodetectors and improved new sensors and light emitters. However, emerging optoelectronic devices rely on large area and low cost fabrication routes to cut manufacturing costs and increase the production throughput. If the exciting properties exhibited photonic structures are to be implemented in these devices then, they too have to be processed in a similar fashion as the devices they intend to improve. In this presentation, I will show how we use soft nanoimprinting lithography to mold unconventional materials such as polymers, cellulose or colloids to produce a variety of photonic architectures exhibiting exciting optical properties that can be seamlessly implemented in sensors, photodetectors and solar cells.
