A silicon-based all-optical wavelength conversion (AOWC) chip is proposed and designed for two-dimensional hybrid multiplexing signals, including mode-division multiplexing (MDM) and wavelength-division multiplexing (WDM). The AOWC chip is structured by mode (de) multiplexers and highly nonlinear silicon waveguide. Tapered directional coupler-based mode (de) multiplexers are used to convert between TE[Formula: see text] and TE[Formula: see text] modes for the signal and pump. The AOWC function is realized using the four-wave mixing (FWM) effect in the multimode silicon waveguide. The on-chip conversion efficiencies are simulated to be [Formula: see text]20.66[Formula: see text]dB and [Formula: see text]20.77[Formula: see text]dB for the TE[Formula: see text] and TE[Formula: see text] mode signals, respectively. The bandwidth is 68.2[Formula: see text]nm, which can support 170 MDM-WDM (85 wavelengths [Formula: see text] 2 modes) hybrid multiplexing channels.
