A full-scale linearized MZI is proposed and experimentally validated by introducing an extremely overcoupled microring. It exhibits triangular-like transmission with a 3-bit improvement in precision while maintaining the same small number of phase shifters. The linearized MZI-based ONN demonstrates higher training accuracy.
