AB - Nanophotonic architectures for classical and quantum optical technology canboost light-matter interaction via sculpturing the optical modes, formingcavities and designing long-range propagation channels. Conventional photonicschemes minimise multiple scattering to realise a miniaturised version ofmacroscopic beam-splitters, interferometers and optical cavities for lightpropagation and lasing. Here instead, we introduce a nanophotonic network builtfrom multiple paths and interference, to control and enhance light-matterinteraction via light localisation beyond single scattering. The network isbuilt from a mesh of subwavelength waveguides, and can sustain localised modesand mirror-less light trapping stemming from interference over hundreds ofnodes. When optical gain is added, these modes can easily lase, reaching$\sim$100 pm linewidths. We introduce a graph solution to the Maxwell'sequation which describes light on the network, and predicts lasing action. Inthis framework, the network optical modes can be designed via the networkconnectivity and topology, and lasing can be tailored and enhanced by thenetwork shape. Nanophotonic networks pave the way for new laser devicearchitectures, which can be used for sensitive biosensing and on-chip opticalinformation processing.
