Integrated, ultrafast all-optical polariton transistors with sub-wavelength grating microcavities
Pietro Tassan, Darius Urbonas, Bartos Chmielak +7
All-optical logic has the potential to overcome the operation speed barrier that has persisted in electronic circuits for two decades. However, the development of scalable architec…
Combined Structural and Plasmonic Enhancement of Nanometer-Thin Film Photocatalysis for Solar-Driven Wastewater Treatment
Desislava Daskalova, Gonzalo Aguila Flores, Ulrich Plachetka +4
Titanium dioxide (TiO) thin films are commonly used as photocatalytic materials. Here, we enhance the photocatalytic activity of devices based on TiO by combining nanostruc…
Phase mask pinholes as spatial filters for laser interference lithography
Giovanna Capraro, Maxim Lipkin, Michael Möller +2
Laser resonators have outputs with Gaussian spatial beam profiles. In laser interference lithography (LIL), using such Gaussian shaped beams leads to an inhomogeneous exposure of t…
