To address this demand, several techniques have been proposed that interleave multiple DACs within a single circuit, introducing new challenges in digital signal processing. In this work, we revisit the principles of interleaved DAC architectures, commonly employed in high-speed converter design. We show that any interleaving scheme, whether in the time domain, frequency domain, or a hybrid of both, can be effectively modeled as a multiple-input multiple-output (MIMO) linear system. This unified framework not only captures the behavior of diverse interleaved architectures but also enables low-complexity digital pre-equalization through a simple MIMO filter. To further streamline implementation, we propose a general algorithm for constructing such equalizers, significantly reducing the design of the associated digital signal processor (DSP). Numerical simulations validate the theoretical framework and demonstrate the effectiveness of the proposed approach.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"16 1","pages":"67-79"},"PeriodicalIF":3.8,"publicationDate":"2025-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11224331","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147429276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among different SiPh devices, Mach–Zehnder interferometers (MZIs) are highly attractive for applications such as modulators, switches, biosensors, and neural networks. However, MZIs are sensitive to fabrication-process variations (FPVs), which can significantly impact MZI performance even with minute changes in the device’s critical dimensions. To address this problem, we present a variation-aware design optimization method for MZIs to minimize optical response shift and changes in free spectral range (FSR), and maximize extinction ratio (ER) under FPVs. We develop detailed analytical models to accurately capture the impact of FPVs in MZIs. Leveraging these models, device layout and design parameters, such as waveguide width, are efficiently explored and optimized based on single-mode and multi-mode design considerations to improve device resilience under FPVs. The simulation results show that, compared to conventional MZIs, our optimized MZIs result in more than a 57% reduction in optical-response shift, as well as FSR and ER changes under FPVs. Moreover, the simulation results show great agreement with the measured optical response of fabricated MZIs. We also present a system-level case study of an MZI-based photonic neural network under FPVs, showcasing up to a 65% improvement in the network inferencing accuracy when using optimized MZIs.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"16 1","pages":"52-66"},"PeriodicalIF":3.8,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147429285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photonic approaches have demonstrated extraordinary potential for some computation-hungry applications like neural networks. In this work, an on-chip electro-optical circuit is proposed to perform FEC decoding tasks with high integration potential and low power consumption characteristics. Leveraging optical computing-friendly algorithmic transformations and a meticulously crafted optical path design, an electro-optical decoder for Reed-Muller (RM) codes is presented. We show by simulation that our proposed decoders achieve a significant computational benefit in energy consumption compared to the standard Dumer’s recursive decoder without an appreciable performance penalty. This on-chip FEC decoder provides a potential solution for improving future FEC hardware with enhanced performance.

In this work, we introduce and analyze a scheme for an all-optical AND logic gate, which allows achieving an almost ideal extinction ratio, a feature that simplifies cascaded architectures for complex operations such as multibit sums and multiplications. We analytically demonstrate how our scheme forces three logical states, namely ‘00’, ‘11’ and ‘10’, to be necessarily ideal in behavior. We also outline the conditions for ideal behavior of the remaining logical state ‘01’, which requires the use of semiconductor optical amplifiers (SOA) in their non-linear operations, by tuning the optical input and feeding current. Our numerical analysis on symmetrically balanced SOAs shows that there are multiple conditions enabling a very small output at logical ‘01’; also, our results suggest that those solutions are strongly influenced by the phase shifts induced in SOAs, which requires to avoid small <inline-formula> <tex-math>$alpha $ </tex-math></inline-formula> factors.

Silicon photonics has emerged as a promising technology for both communication and computation in accelerating deep learning workloads. Existing photonic accelerators focus on either designing monolithic photonic computing cores or using photonic interconnects with electronic cores for deep neural network (DNN) acceleration. However, the integration of photonic computing within many-core photonic interconnect architectures has not been extensively studied. In this paper, we propose a novel scalable chiplet-based photonic accelerator named SIPHON that leverages both photonic computing and communication for ultrafast and energy-efficient DNN training and inference. A photonic interconnection with dynamically configurable multiple communication modes is proposed to address the broad wavelength and bandwidth demands of general photonic computing cores. We design a photonic computing unit (PCU) for the multiply-accumulate operations and gradient computations in forward and backward propagations. A dataflow is developed to facilitate efficient data reuse and parallel computing by leveraging multiple communication modes. To validate SIPHON’s photonic computing, we prototype the optical platform using FPGA, RF, and photonic devices.
