Mode-order converters drive the on-chip applications of multimode silicon photonics. Here, we propose a TM0-to-TM3 mode-order converter by leveraging a shallowly etched slot metasurface pattern atop the silicon waveguide, rather than as some previously reported TE-polarized ones. With a shallowly etched pattern on the silicon waveguide, the whole waveguide refractive index distribution and the corresponding field evolution will be changed. Through further analyses, we have found the required slot metasurface pattern for generating the TM3 mode with high conversion efficiency of 92.9% and low modal crosstalk <−19 dB in a length of 17.73 μm. Moreover, the device’s working bandwidth and the fabrication tolerance of the key structural parameters are analyzed in detail. With these features, such devices would be beneficial for the on-chip multimode applications such as mode-division multiplexing transmission.

Optical Wavelength Conversion

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.
