“…The chip-to-chip interconnect requires efficient means of coupling light from on-chip transceivers to a communication link. In both free-space and fibre systems, this can be achieved using a grating coupler 20,[44][45][46] that preserves and launches all spatial modes perpendicular to the chip.…”

The use of optical interconnects has burgeoned as a promising technology that can address the limits of data transfer for future high-performance silicon chips. Recent pushes to enhance optical communication have focused on developing wavelength-division multiplexing technology, and new dimensions of data transfer will be paramount to fulfill the ever-growing need for speed. Here we demonstrate an integrated multi-dimensional communication scheme that combines wavelength- and mode- multiplexing on a silicon photonic circuit. Using foundry-compatible photonic inverse design and spectrally flattened microcombs, we demonstrate a 1.12-Tb/s natively error-free data transmission throughout a silicon nanophotonic waveguide. Furthermore, we implement inverse-designed surface-normal couplers to enable multimode optical transmission between separate silicon chips throughout a multimode-matched fibre. All the inverse-designed devices comply with the process design rules for standard silicon photonic foundries. Our approach is inherently scalable to a multiplicative enhancement over the state of the art silicon photonic transmitters.

“…Communication between nodes requires an efficient means of coupling light from the on-chip modulators to a communication link. In both free space and fibre systems, this can be achieved using a beam emitter 26,38,39 that preserves and launches all spatial modes perpendicular to the chip. Here, we feed an inverse-designed surface-normal beam emitter with an adiabatically tapered multi-mode waveguide to maintain the mode profiles (Inset 1 of Fig.…”

Modern microelectronic processors have migrated towards parallel computing architectures with many-core processors. However, such expansion comes with diminishing returns exacted by the high cost of data movement between individual processors. The use of optical interconnects 1,2 has burgeoned as a promising technology that can address the limits of this data transfer. While recent pushes to enhance optical communication have focused on developing wavelength-division multiplexing technology, this approach will eventually saturate the usable bandwidth, and new dimensions of data transfer will be paramount to fulfill the ever-growing need for speed 3-6 . Here we demonstrate an integrated intra-and inter-chip multi-dimensional communication scheme enabled by photonic inverse design. Using broad-band inverse-designed mode-division multiplexers, we combine wavelength-and mode-multiplexing of data at a rate exceeding terabit-per-second. Crucially, as we take advantage of an orthogonal optical basis, our approach is inherently scalable to a multiplicative enhancement over the current state of the art.

“…Grating couplers have also been developed for achieving coupling between a multimode waveguide and a few-mode fiber. [73,74] For example, in Ref. [74], the coupling efficiency is −10.6 dB, while the mode-dependent coupling efficiency is approximately 3.7 dB.…”

The field of silicon nanophotonics has attracted considerable attention in the past decade because of its unique advantages, including complementary metal-oxide-semiconductor (CMOS) compatibility and the ability to achieve an ultra-high integration density. In particular, silicon nanophotonic integrated devices for on-chip light manipulation have been developed successfully and have played very import roles in various applications. In this paper, we review the recent progress of silicon nanophotonic devices for on-chip light manipulation, including the static type and the dynamic type. Static onchip light manipulation focuses on polarization/mode manipulation, as well as light nanofocusing, while dynamic on-chip light manipulation focuses on optical modulation/switching. The challenges and prospects of high-performance silicon nanophotonic integrated devices for on-chip light manipulation are discussed.
