A theoretical approach to the optical properties of the 2D and 3D photonic crystals which yields further insight in the phenomenon of the reflection from different families of lattice planes in relation to the presence of photonic gaps or photonic bands. We calculate the photonic bands and optical properties of LiNbO3 based photonic crystals. Calculations of reflection and transmission spectra show the features correspond to the onset of diffraction, as well as to additional reflectance structures at large values of the angle of incidence. © 2013 Copyright Taylor and Francis Group, LLC.EnglishPhotonic band gaptransmission spectrum3D photonic crystalsAngle of IncidenceBand structure calculationPhotonic bandsPhotonic structureReflection and transmissionTheoretical approachTransmission spectrumsBand structureFerroelectric materialsFunctional materialsPhotonic band gapOptical propertiesArticle10.1080/00150193.2013.8222721563-5112
