Aufbau einer Interferenzlithografie-Anlage zur Herstellung photonischer Kristalle
Multiple laser beam interference allows to produce periodic light patterns in the order of the wavelength of light. A simulation program helps to identify different patterns and to investigate the influence of changing parameters such as e.g. the angle of incidence or the polarization. A positive photoresist (Shipley S1805) is used to create two-dimensional metallic photonic crystals by UV interference lithography.
