“…Detailed spacing-and data rate-dependent BER measurements show co-optimization of per-channel data rate with 𝜆 ag to be a promising strategy to scale link bandwidth, enabling the multi-FSR designs to limit the requisite additional power penalties to off-resonance (≤ 0.02 dB per-channel) and routing losses. Additionally, many of the various wavelength-division multiplexing-compatible MDM architectures have been demonstrated in the silicon photonics platform [10,11] can be trivially extended to accommodate the IM-DD DWDM architecture, leveraging spacial modes as an orthogonal axis for multiplicative DWDM and MDM scaling. The advances presented in this work illustrate a promising trajectory for the practical use of Kerr-driven silicon photonic interconnects in data centers.…”

The use of chip-based micro-resonator Kerr frequency combs in conjunction with dense wavelength-division multiplexing (DWDM) enables massively parallel intensity-modulated direct-detection (IM-DD) data transmission with low energy consumption. Resonator-based modulators and filters used in such systems can limit the number of usable wavelength channels due to practical constraints on the maximum achievable free spectral range (FSR). In this work, we introduce the design of multi-Tb/s comb-driven resonator-based silicon photonic links by leveraging the multi-FSR regime. We demonstrate the viability of the link architecture with yield estimates that are supported by extensive wafer-scale measurements of 704 micro-resonators fabricated in a commercial complementary metal–oxide–semiconductor (CMOS) foundry. We show that a 2.80 Tb/s link is realizable with a ≥ 6σ yield (~99.999%), and aggregate bandwidths of 3.76 Tb/s and 4.72 Tb/s are possible if yield targets are relaxed (3σ and 1σ respectively). All designs represent a 1.94—3.28× boost to aggregate link bandwidth while maintaining BER ≤ 10−10 performance, with a theoretical bandwidth of 10.51 Tb/s being possible for sufficiently robust resonators. High-speed BER measurements informed co-optimization of data rate and aggressor spacing (λag), limiting any additional loss-based power penalties to off-resonance insertion loss (IL) and routing loss. This work demonstrates that, through the multi-FSR regime, there is a clear path toward Kerr comb-driven ultra-broadband, high bandwidth silicon photonic links that can support next-generation data centers and high performance computers.

“…It can be mentioned that important steps towards ultra-compactness of photonic circuits have been made very recently via either anisotropic metamaterials [ 95 ] or photonic inverse design [ 96 , 97 , 98 ]. As an example, a polarization beam splitter (PBS), which is an important device in PICs for multiplexing and demultiplexing polarizations, was designed and fabricated on a silicon-on-insulator (SOI) platform using a directional coupler with single-mode waveguides 500 nm wide; the coupling region was designed by tailoring the anisotropic metamaterial, which was composed of identical periodic subwavelength strips.…”

The combination of integrated optics technologies with nonlinear photonics, which has led to growth of nonlinear integrated photonics, has also opened the way to groundbreaking new devices and applications. In a companion paper also submitted for publication in this journal, we introduce the main physical processes involved in nonlinear photonics applications and discuss the fundaments of this research area. The applications, on the other hand, have been made possible by availability of suitable materials with high nonlinear coefficients and/or by design of guided-wave structures that can enhance a material’s nonlinear properties. A summary of the traditional and innovative nonlinear materials is presented there. Here, we discuss the fabrication processes and integration platforms, referring to semiconductors, glasses, lithium niobate, and two-dimensional materials. Various waveguide structures are presented. In addition, we report several examples of nonlinear photonic integrated devices to be employed in optical communications, all-optical signal processing and computing, or in quantum optics. We aimed at offering a broad overview, even if, certainly, not exhaustive. However, we hope that the overall work will provide guidance for newcomers to this field and some hints to interested researchers for more detailed investigation of the present and future development of this hot and rapidly growing field.

“…Instead of random backscatter-ing, we achieve SIL via programmable synthetic reflection, dramatically increasing the access to laser detunings that support DKS. The synthetic reflection is generated via photonic crystal ring resonators (PhCR) [40], which have recently received growing attention in integrated nonlinear photonics [41][42][43][44][45]. In addition, we show that robust access to SIL-based DKS can be combined with recent results of spontaneous single-DKS generation in PhCRs (avoiding non-solitonic states) [41].…”
