Integrated optical unitary converter (OUC) is re-ceiving a great interest for optical communication, quantum computing, and deep learning applications. Previously demonstrated OUCs assume a fixed wave-length and a polarization state at the input. In this paper, we demonstrate that the multi-plane light conversion (MPLC)-based OUC with multiport directional couplers (DCs) can provide arbitrary and independent unitary conversions to dual-polarization multiple-wavelength channels at the same time. This is due to the inherent flexibility of the MPLC concept as well as strong polari-zation/wavelength dependence of a silicon-photonic mul-tiport DC.
