Master thesis – Photonic integrated circuits imprinted with Step and Repeat nanoimprint lithography

A photonic integrated circuit (PIC) is a device with integrated photonic functionality and is therefore very similar to an electronic integrated circuit. The main difference between the two is that photonic integrated circuits provide functions for information signals based on light wavelengths, usually in the visible spectrum or near infrared (850 nm – 1650 nm). One promising application is the realization of PICs for solid state LIDARs based on an optical phased array. Typically, many steps are required in order to realize a PIC. However, it is possible to realize a PIC in significantly fewer process steps if nanoimprint lithography (NIL) is used in combination with high refractive materials. This is done by pressing a nanostructured stamp into a liquid UV-curable high refractive index material on a substrate. While the stamp is in contact, the material is cured by UV-irradiation and then the stamp is removed, resulting in a nanostructured high refractive index polymer on the substrate.

PROFACTOR is an applied research center located in Steyr. We conduct research in the field of additive micro/nano manufacturing and industrial assistive systems. Our team consists of around 70 employees from 15 different academic fields. We work across disciplines to find solutions for the manufacturing industry and set standards in robotics, machine vision, simulation, 3D printing, functional surfaces and nanostructures.

Your tasks

The goal of the thesis is
