Their optical characteristics arise from the mode field distributions and propagation constants, which determine the beam evolution inside the waveguides. Solving the modes of the optical waveguides is usually achieved by the transformation of the Maxwell equations into the linear equations, and hence, the computational complexity lies in the size of the matrix for the eigenvalue problem. Generally, the matrix size is determined by the grid size and therefore, it becomes quite time consuming to solve the two-dimensional full vectorial waveguide modes. In this work, a perfectly matched layer (PML) mode expansion method is proposed to find the full vectorial modes. The pseudo modes related to the PML boundary, which can serve as the basis functions to expand the waveguide modes, have explicit analytical formulations for the mode fields and propagation constants. The matrix size of the linear equation is reduced to the number of pseudo modes and henceforth, the computational cost is significantly reduced. Since the PML modes significantly reduce the reflection at the boundary, the accuracy for waveguide mode evaluation is highly guaranteed. Even for the leaky modes, the proposed full vectorial mode solver gives accurate predictions both for the mode fields and the propagation constants. The proposed method is expected to significantly reduce the computational cost for the design and analysis of the integrated photonic system while maintaining an acceptable accuracy.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 3","pages":"7700208-7700208"},"PeriodicalIF":2.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11523022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Frequency modulated continuous wave (FMCW) LIDARs are an important type of LIDARs for their coherent detection signature. However, achieving tunable laser with large sweep bandwidth, high modulation frequency and linear sweep simultaneously for FMCW LIDARs is extremely difficult for current laser techniques. In our recent work [1], we address these challenges by using an photonic microcomb to calibrate a Fourier domain mode-locked (FDML) laser. The microcomb provides a precise frequency reference as well as a large line spacing to calibrate the FDML laser with ultrahigh chirp rates (up to 320 PHz/s) for transform-limited ranging. The fully calibrated FDML laser enables a normalized ranging precision as high as 0.27 nm<inline-formula><tex-math>$cdot sqrt{mathrm{s}}$</tex-math></inline-formula> (record for FMCW LIDARs). We further established a theoretical framework to correct velocity errors induced by nonlinear sweeps, refreshing insights in FMCW velocity measurement. This approach highlights the potential of microcomb-assisted calibration for advancing ultrafast LIDAR and precision optical sensing. We also briefly review recent advances in broad swept laser and FMCW LIDAR, particularly those reported in 2025. Our work elevates the performance of FMCW LIDARs to a new level and elucidates how integrated photonics can unlock the potential of broadband, imperfectly swept lasers.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 3","pages":"3100208-3100208"},"PeriodicalIF":2.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11520241","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148509705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A dataset comprising 150 SHG–rSHG paired images was processed using the Huygens Professional deconvolution software with three standard presets and empirically optimized modality-specific settings, applied both with and without rolling-ball background subtraction. Metric responses were first examined on raw images and under controlled Gaussian blur, revealing four characteristic response patterns associated with differing sensitivities to resolution degradation, local texture variations, and image smoothness. Based on these observations, CLIP-IQA, PIQUE, NIQE, and CNNIQA were selected for a detailed assesment of deconvolution outcomes. Although rSHG images consistently displayed higher apparent resolution and generally showed greater improvement after deconvolution than SHG images, the evaluated metrics did not converge on a single optimal parameter set or preprocessing strategy. Metrics emphasizing resolution tended to penalize background subtraction and aggressive deconvolution, whereas smoothness-oriented metrics favored more regularized reconstructions, leading to a pronounced negative correlation between the two groups. These results indicate that NR-IQA metrics capture competing aspects of image quality in SHG/rSHG imaging and should therefore be interpreted as complementary, application-dependent indicators rather than absolute measures of quality.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 3","pages":"6900507-6900507"},"PeriodicalIF":2.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11505769","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148514365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although machine learning is effective for OAM recognition, most methods rely on large labeled datasets, which are costly to obtain underwater. Unsupervised learning alleviates this limitation by enabling label-free representation learning, reducing data costs and improving adaptability in complex marine environments. Motivated by these advantages, this paper proposed an Alpha Evolution optimized unsupervised extreme learning machine (AE-US-ELM). Without labeled samples, intensity features of OAM-carrying LG beams under varying turbulence and transmission distances are used for training. In addition, the AE algorithm optimizes US-ELM hyperparameters for different turbulence strengths and transmission distances. The constructed autonomous model enables analytical OAM mode identification without manual parameter tuning, while delivering superior recognition performance. Experimental results show that AE-US-ELM consistently achieves superior performance across turbulence strengths and distances, outperforming several representative unsupervised and optimization-based approaches, providing a computationally efficient and robust solution for practical underwater scenarios.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 3","pages":"1-9"},"PeriodicalIF":2.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11482060","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148507423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective of this work is to enable efficient and cost-effective data muling from underwater sensors by investigating the use of optical wireless communications to transmit data from the underwater sensors to an aerial node close to the water surface, such as an unmanned aerial vehicle (UAV).More specifically, we utilize a direct water-to-air (W2A) optical communication link between the sensor node equipped with an LED emitter and the UAV equipped with an ultra-sensitive receiver, i.e., a silicon photo-multiplier. As a main contribution, we develop a comprehensive Monte Carlo–based ray-tracing algorithm to characterize this complex channel. This framework rigorously incorporates the impact of air bubbles modeled through the Mie scattering theory, a realistic sea surface representation derived from the JONSWAP spectrum, and an analytical derivation of the channel loss resulting from UAV instability under wind-induced perturbations. Furthermore, we conduct a comprehensive analysis of the W2A channel, examining the influence of key parameters such as wind speed, transmitter configurations, and receiver characteristics.
