Photonic crystals are a promising platform for integrated optical hybrid networks on the single photon level. In the last years the controlled coupling of single emitters to photonic crystal cavities has been strikingly demonstrated in several experiments [1]. For future integrated single photon devices efficient wave guiding and coupling structures will be needed. The latter ones are particularly important, as they form the interface between photonic chips and the macroscopic measurement equipment. Our latest results on the design and fabrication of high efficient couplers with large directivity, as well as their integration into photonic networks are presented.
