Photonic crystals bear the potential to improve the light extraction from scintillator crystals used in high energy physics and medical imaging applications. Because of their periodic structure with dimensions in the range of the wavelength of incident light, photonic crystals can manipulate photon propagation in a significant way. In this study, Rigorous Coupled Wave Analysis has been used in conjunction with Monte Carlo simulations to investigate the performance of two-dimensional photonic crystal coatings for various scintillator configurations, including different geometries and crystal wrappings. Their impact on the detector performance is discussed and preparations of the experimental verification are presented.
