| Abstract [eng] |
Light propagation in photonic crystals is governed by their dispersion properties, which can be controlled by precisely selecting photonic crystal parameters. In such a way, various and sometimes exotic phenomena can be realized. Three-dimensional photonic crystals have the highest number of possible phenomenon, but on the other hand, such crystals are the most difficult to fabricate due to the lack of suitable technologies. In this Thesis it is shown, that various light propagation phenomena (structural colors, flat lensing, spatial filtering and super-collimation) can be realized in photonic crystals with larger and technologically less demanding periods, mainly by using higher order photonic bands dispersion properties. Such photonic crystals were fabricated by direct laser writing techniques in photopolymers and glasses. Their performance was evaluated both experimentally and numerically. . |
