|Issue Date:||2019||Publisher:||OSA - The Optical Society||Abstract:||The idea of the angular, or equivalently - spatial, filtering by photonic crystals (PhCs) is based on a selective diffraction of the light propagating through the double-periodic photonic structure. The angular components of the incident light at a resonance with the transverse and longitudinal periodicities of the structure diffract efficiently and are removed from the zero-diffraction order of the transmitted beam. On the other hand, the propagation of the angular components that are out of the resonances is unaffected. Therefore, the angular/spatial filtering can be obtained by a suitable geometry of the PhCs. This idea already proven itself as a useful alternative to conventional spatial filtering techniques, and is being implemented in several applications, for instance for intracavity angular filtering in microlasers . © 2019 IEEE||Description:||The European Conference on Lasers and Electro-Optics, CLEO_Europe_2019 -- 23 June 2019 through 27 June 2019 -- 142098||URI:||https://hdl.handle.net/20.500.11851/9935||ISBN:||9.78E+12|
