FEderated Edge Learning (FEEL) is an advanced paradigm in edge artificial intelligence, enabling privacy-preserving collab.rative model training through periodic communication between edge devices and a central server. FEEL involves three key processes: sensing, computation, and communication for data acquisition, processing, and exchange, respectively. Due to limited system resources, optimizing each process individually may lead to suboptimal learning performance. This challenge has sparked research into Integrated Sensing-Computation-communication (ISCC) design for enhanced FEEL. While previous work has optimized general learning parameters such as batch size and computing frequency, there is a lack of customized designs considering the neural network architecture as an optimizable variable in ISCC for FEEL. To close this gap, we introduce a novel design where each device generates a sub-model through controllab.e weight dropout, adding flexibility by directly manipulating the learning process and reducing computation and communication overhead. To guide ISCC resource allocation in this new setting, we present a comprehensive convergence analysis, revealing the tight coupling of sensing, computation, and communication across devices and their impact on FEEL convergence. Building on these theoretical insights, we formulate an ISCC problem aiming to maximize the FEEL convergence rate through joint optimization of variables such as batch size, sensing power, dropout rate, and communication power. This non-convex problem is decomposed into two sub-problems via alternating optimization: one controls batch size using a sorting algorithm, while the other focuses on ISCC device parameters, transformable into a convex problem solved by successive convex approximation. Extensive experiments using human motion recognition datasets demonstrate the superiority of the proposed design over baseline schemes. © 2014 IEEE.

With advantages of high-precision 3D imaging and simultaneous measurement of target distance and velocity, frequency modulated continuous wave (FMCW) LiDAR has great potential in the fields of autonomous driving, military and aerospace. However, frequency-modulated (FM) nonlinearity significantly deteriorates its ranging accuracy and has become a problem that cannot be neglected. This paper proposes an arbitrary waveform FMCW (AW-FMCW) system, in which the distance of target is extracted precisely irrespective of the FM waveform employed. In proposed AW-FMCW system, the correlation between the phase of coherent signal and the FM waveform of tunable laser is rigorously deduced and analyzed. The distance of target is extracted utilizing minimum mean square error (MMSE) estimation. The low-bandwidth short-distance (LBSD) approximation is proposed to simplify the process of the estimation and quadrature coherent detection is employed to acquire the phase signal. The performance in terms of the measured distance and the precision of AW-FMCW system is theorized in detail and validated by Monte-Carlo simulations and experiments. In the experiments, three different FM waveforms are utilized for ranging of targets at six different distances, and 0.279 mm ranging precision and 1.35×10-4 relative precision are realized at 2.06 m target detection. © 1963-2012 IEEE.

Inhibitory dynamics plays an important role in the information processing of biological spiking neurons, where incoming stimuli weaken the activity level of neurons. Due to the lack of prohibitive physical effects in photonics, the realization of the photonic spiking neuron (PSN) with intrinsic inhibitory dynamics and the application of efficient inhibitory dynamics in the optical domain have been challenging. Herein, we propose a PSN with all-optical inhibitory dynamics, which is achieved by intrinsic backscattering from the unidirectional-emitted semi-conductor ring laser (SRL) to the master laser. The photonic spiking dynamics of the SRL operating in unidirectional mode were investigated, demonstrating the computational properties of the PSN as a leaky integrate-and-fire neuron. We prove that as the backscattering intensity increases, the number of spikes generated under the same input signal decreases. Under the influence of backscattering, the number of spikes fired increases with the input signal rate. In the speech signal classification task, the classification accuracy improves from 89% to 94% under the influence of inhibitory dynamics. This suggests that the presence of inhibitory dynamics helps filter out unwanted interference information. The results show the potential of backscattering-based inhibition dynamics for facilitating advanced neuromorphic information processing. © 2009-2012 IEEE.

This paper proposes a novel sixth-generation (6G) multi-modal intelligent vehicle-to-vehicle (V2V) channel model from light detection and ranging (LiDAR) point clouds based on Synesthesia of Machines (SoM). To explore the mapping relationship between physical environment and electromagnetic space, a new V2V high-fidelity mixed sensing-communication integration simulation dataset with different vehicular traffic densities (VTDs) is constructed. Based on the constructed dataset, a novel scatterer recognition (ScaR) algorithm utilizing neural network SegNet is developed to recognize scatterer spatial attributes from LiDAR point clouds via SoM. In the developed ScaR algorithm, the mapping relationship between LiDAR point clouds and scatterers is explored, where the distribution of scatterers is obtained in the form of grid maps. Furthermore, scatterers are distinguished into dynamic and static scatterers based on LiDAR point cloud features, where parameters, e.g., distance, angle, and number, related to scatterers are determined. Through ScaR, dynamic and static scatterers change with the variation of LiDAR point clouds over time, which precisely models channel non-stationarity and consistency under different VTDs. Some important channel statistical properties, such as time-frequency correlation function (TF-CF) and Doppler power spectral density (DPSD), are obtained. Simulation results match well with ray-tracing (RT)-based results, thus demonstrating the necessity of exploring the mapping relationship and the utility of the proposed model.

Directivity-Aware Degrees of Freedom Analysis for Extremely Large-Scale MIMO

Extremely large-scale multiple-input multiple-output (XL-MIMO) communications, enabled by numerous antenna elements integrated into large antenna surfaces, can provide increased effective degree of freedom (EDoF) to achieve high diversity gain. However, it remains an open problem that how the EDoF is influenced by the directional radiation pattern of antenna elements. In this work, empowered by the wavenumber-domain channel representation, we analyze the EDoF in a general case where the directivity of antennas, determined by the antenna structure and element spacing, is considered. Specifically, we first reveal the uneven distribution of directivity-aware wavenumber-domain coupling coefficients, i.e., channel gain towards different directions, in the isotropic Rayleigh fading channel. EDoF is then calculated based on such distribution of coupling coefficients. A numerical method is also provided to obtain coupling coefficients via full-wave EM simulations. Due to the influence of antenna directivity, how EDoF and ergodic channel capacity vary with the element spacing are explored via simulations for different antenna types. © 1967-2012 IEEE.

optical frequency comb serves as precise rulers in physical quantity measurements, using the Vernier measurement principle by configuring a multi-comb system. We propose a non-ambiguous microwave frequency measurement system based on triple comb generated by electro-optic modulation. The triple combs with slightly different repetition rates sample the unknown microwave signal. Utilizing mathematical principles of non-ambiguous measurement, the system achieves high-precision static signal measurements and real-time dynamic signal tracking. Limited by the modulation bandwidth of modulator, the system attains a detection range from 0 to 30 GHz. Leveraging the electro-optic comb’s flexibility, optical comb repetition rates can be tailored to receiver bandwidths. The dynamic range of microwave signal power is from -30 dBm to -10 dBm. In instantaneous frequency measurement of dynamic signal, errorfree measurement can be achieved at a resolution of 1 MHz. The spectral stability of the triple combs based on electro-optic modulation is not affected by temperature and vibration, which ensures that the microwave frequency measurement has a high robustness in a variety of measurement environments. © 1989-2012 IEEE.

Arbitrary control of the flow of light using pseudomagnetic fields in photonic crystals at telecommunication wavelengths

arXiv 2025年

In photonics, the idea of controlling light in a similar way that magnetic fields control electrons has always been attractive. It can be realized by synthesizing pseudomagnetic fields (PMFs) in photonic crystals (PhCs). Previous works mainly focus on the Landau levels and the robust transport of the chiral states. More versatile control over light using complex nonuniform PMFs such as the flexible splitting and routing of light has been elusive, which hinders their application in practical photonic integrated circuits. Here we propose an universal and systematic methodology to design nonuniform PMFs and arbitrarily control the flow of light in silicon PhCs at telecommunication wavelengths. As proofs of concept, a low-loss S-bend and a highly efficient 50:50 power splitter based on PMFs are experimentally demonstrated. A high-speed data transmission experiment is performed on these devices to prove their applicability in real communication systems. The proposed method offers a new paradigm for the exploration of fundamental physics and the development of novel nanophotonic devices. Copyright © 2025, The Authors. All rights reserved.

In the information explosion era, the demand for high-density stable storage technologies is soaring. Multi-dimensional optical storage with femtosecond laser writing offers a potential solution for massive data storage. However, equipment instability and reduced voxel resolution inevitably lead to data errors. Here, we propose and demonstrate a paradigm exemplifying high-fidelity eternal lifetime optical storage enabled by error correction mechanism. We increase information density by reducing voxel size and spacing. Leveraging deep learning methods, we achieve 8-bit voxel encoding and a storage capacity of 2.15 Tb/disc. We implement the Reed-Solomon(RS) algorithm for error-free data recovery and get the trade-off between the storage capacity and the redundancy length. Our storage paradigm takes advantage of error-correcting codes, together with permanent information storage capabilities of extremely stable fused silica, marking a significant advancement for recording massive data to the application level and making it possible to faithfully record the information generated in human civilization. © 2025, CC BY-NC-SA.
