We experimentally demonstrate a very short, low-loss, and broadband on-chip linear optical logic gate. By tuning a bias input of a Y+1 gate integrated with silicon photonics, we observed AND/NOR operations with the binary contrast of > 9 dB. This may be crucial as one of components in low-latency computational circuits exceeding physical limitations of conventional electronic circuits.
