“…Thermal crosstalk is another important performance metrics for dense integration and PIC miniturization. In this work, owing to the thermally isolating cladding, 3.6 % thermal crosstalk is measured at a 13 µm pitch, which is close to best results obtained on Si [28], [43], [44]. The design, simulation, fabrication procedure, and measurement results will be included in the following sections.…”

“…It can be seen from the orange line that as the distance between an MR pair increases, the amount of phase crosstalk reduces exponentially. Such a trend has also been observed in [24]. To find a balance between tuning power savings while having reduced crosstalk, we perform a sensitivity analysis based on the distance between two adjacent MRs in our architecture.…”

Domain-specific neural network accelerators have seen growing interest in recent years due to their improved energy efficiency and inference performance compared to CPUs and GPUs. In this paper, we propose a novel cross-layer optimized neural network accelerator called CrossLight that leverages silicon photonics. CrossLight includes device-level engineering for resilience to process variations and thermal crosstalk, circuit-level tuning enhancements for inference latency reduction, and architecture-level optimization to enable higher resolution, better energy-efficiency, and improved throughput. On average, CrossLight offers 9.5× lower energy-per-bit and 15.9× higher performance-per-watt at 16-bit resolution than state-of-the-art photonic deep learning accelerators.

“…Methods including air-gap trench or silicon substrate undercut post-processing, folded waveguide, and multi-pass waveguide have been proposed and demonstrated. A trade-off between the power consumption and the thermal time constant has also been investigated [46,47]. In this paper, we give an overview of the current status of the TOPS based on silicon photonics technologies.…”

Silicon photonic platforms offer relevance to large markets in many applications, such as optical phased arrays, photonic neural networks, programmable photonic integrated circuits, and quantum computation devices. As one of the basic tuning devices, the thermo-optic phase shifter (TOPS) plays an important role in all these applications. A TOPS with the merits of easy fabrication, low power consumption, small thermal time constant, low insertion loss, small footprint, and low crosstalk, is needed to improve the performance and lower the cost of the above applications. To meet these demands, various TOPS have been proposed and experimentally demonstrated on different foundry platforms In this paper, we review the state-of-the-art of TOPS, including metal heater, doped silicon, silicide, with silicon substrate undercut for heat insulation, folded waveguide structure, and multi-pass waveguide structure. We further compare these TOPSs and propose the directions of the future developments on TOPS. Graphical abstract
