A tuning algorithm is needed for a previously demonstrated phased array antenna system using an integrated optical beamforming network (OBFN). The optical delays in the OBFN are realized by cascading optical ring resonators (ORRs), which can be tuned by varying their parameters. In this paper an algorithm is presented that converts a set of desired delay values into the set of ORR parameters that minimizes the phase error.
