Our former colleague Marcus Ossiander is a guest at the Deutsches Museum this Wednesday. As part of the lecture series “Science for Everyone”, he will explain what modern lenses and processors have in common.
With the help of tiny nanotowers made of silicon or glass, which are smaller than many bacteria and are produced using the manufacturing methods of modern semiconductor technology, it is now possible to change the oscillation state of light on the nanoscale. This means that light can be focused and imaged without passing through a "real" lens. On the one hand, this new technology allows us to produce ultra-flat lenses - they are flatter than a human hair and are therefore ideal for smartphone cameras, for example - or achromatic optics, which can be used very well as colour-independent lenses in microscopy, for example. Furthermore, it is now possible to realise optical elements that fulfill completely new functions. Examples of this are the generation of light beams that have an angular momentum, the development of cameras that recognise polarisation, or the further shortening of the duration of already ultra-short light flashes. Marcus Ossiander will present the basics, manufacturing and unique physical applications that arise from the new design possibilities.
