Photonic crystals [1] are a promising platform for integrated quantum networks. In recent years, coupling of single emitters to photonic crystal cavities as first step towards such systems has been demonstrated [2].

Additional key ingredients are efficient photon guiding and coupling to the far-field. The latter is crucial since it forms the interface between photonic chips and the macroscopic measurement environment.

We present our latest results on the design and characterization of efficient grating couplers with large directivity and small footprint, as well as their integration into photonic networks.
