R&D Projects GJ16-09692Y GA ČR - Czech Science Foundation (CSF) Institutional support FZU-D - RVO:68378271 Annotation Photonic crystal (PhC) slabs can be used for effective extraction of photoluminescence (PL) from bulk material via leaky modes. The effectivity of light extraction depends on various factors e.g. refractive index contrast, lattice type, or physical dimensions of PhC. In this study, we compare the optical properties, particularly the light extraction efficiency into near-normal direction, of nanocrystalline diamond PhC slabs with square lattice. The PhC structures with various physical (PhC lattice constant, layer thickness, column height) and material (morphology of diamond layer) properties were investigated. We show that more than 100-times PL enhancement may be achieved. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2018
