Characterisation of 3D-printed micro-structures for optics

Bachelor thesis | Natuurkunde (BSc)

This research explores the possibility of producing acrylic micro-structures for optical purposes with a Nanoscribe 3D-printer, which uses two-photon polymerisation. More specifically, it tries to characterise the effect of inherent flaws of the 3D-printing production method on far-field transmission optics. The studied samples are gratings with different periodicities ranging from 4 to 1 mm and samples with flat and tilted surfaces. The gratings show optical effects from variations in displacement, duty-cycle and height, and scattering effects from writing lines. Steps are taken towards 3D-printing multi-grating layer samples, with the end goal of producing a woodpile structure and other multi-layer photonic crystals.
