In photonic decision-making, the cross-correlation value is conventionally used to determine the leader-laggard relationship observed in mutually coupled semiconductor lasers. However, it has a problem of higher computational cost than the method of other photonic decision-making. In this study, we introduce a new method to determine the leader-laggard relationship using detuning between optical frequency and experiment with this method by 90° optical hybrid. Using this method, we analyze the multi-arm bandit problem and demonstrate that it is capable of faster decision-making than the conventional method.
