Freeform terahertz structures fabricated by multi-photon lithography and metal coating

Pascal Maier, Alexander Kotz, Joachim Hebeler +10

Direct-write multi-photon laser lithography (MPL) combines highest resolution on the nanoscale with essentially unlimited 3D design freedom. Over the previous years, the groundbrea…

3D-printed facet-attached optical elements for beam shaping in optical phased arrays

Stefan Singer, Yilin Xu, Sebastian Tobias Skacel +10

We demonstrate an optical phased-array (OPA) equipped with a 3D-printed facet-attached element for shaping and deflection of the emitted beam. The beam shaper combines freeform ref…

Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit

Sebastiaan Y. Haffert, Robert J. Harris, Alessio Zanutta +31

Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanets atmosphere, but most direc…
