We present a graph-based model for multiple scattering of light in integrated lithium niobate on insulator (LNOI) networks, which describes an open network single-mode waveguides with tunable at the nodes. first validate small scale experimental LNOI resonator devices and show consistent agreement between simulated measured spectral data. Then, is used to demonstrate novel platform on-chip large-scale optical networks up few hundred nodes, behaviour tailored disorder. Combining our simple material properties LNOI, this creates new opportunities control randomness large networks.
