4.36 Tbit/s Silicon Chip-to-Chip Transmission via Few-Mode Fiber (FMF) using 2D Sub-wavelength Grating Couplers

We demonstrate a high-speed silicon chip-to-chip few-mode-fiber (FMF) transmission via 2D sub-wavelength grating-couplers. The design and characterization of the proposed silicon device are discussed. A total FMF transmission capacity of 4.36 Tbit/s is achieved.
