Misalignment between the mask and wafer is the main factor affecting overlay accuracy. The photolithographic alignment method, which uses Moiré fringes, is notable for its straightforward optical path and high precision. However, the alignment accuracy is significantly influenced by the Moiré fringe phase analysis algorithm. This paper proposes a hybrid deep learning architecture based on a Vision Transformer for Moiré fringe phase analysis. By training on various types of Moiré fringe datasets, the model can predict the fringe wrapping phase, allowing for the analysis of elements within the wrapping phase, including displacement information. This method combines the multi-head attention mechanism of a Vision Transformer with deep learning feature extraction to build a hybrid deep learning architecture. This model effectively learns the mathematical mapping between the Moiré fringe phase information and actual offset, accurately outputting true Moiré fringe phase data. Results show that despite the presence of Gaussian noise and tilted states, the hybrid architecture maintains a Root Mean Square Error (RMSE) within the range of 6–7 nm, and a Structural Similarity Index (SSIM) above 0.70, and Peak Signal-to-Noise Ratio (PSNR) is consistently maintained above 36. Consequently, the proposed model demonstrates superior robustness in handling noisy data compared to existing phase retrieval techniques. Additionally, the model has been optimized in structure to more efficiently extract phase information from complex Moiré fringe patterns. This study offers valuable insights for expanding Moiré fringe imaging applications.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970258","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072810","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}

This study focuses on the development of a high-power 1018 nm single-frequency narrow-linewidth fiber laser amplifier based on a DBR single-frequency seed source. The DBR seed source, constructed using an 8 mm-long doped fiber, achieves a linewidth of 3.25 kHz and demonstrates a wavelength tuning range exceeding 1.51 nm across a temperature range of −10 <inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>C to 120 <inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>C. The tuning process exhibits excellent linearity between wavelength and temperature, with no observed mode hopping. To ensure high ASE and SBS suppression in the amplified output, a four-stage amplification and filtering scheme was implemented. By carefully selecting optical fibers and optimizing their lengths, the system achieves an output power exceeding 120 W for the 1018 nm single-frequency laser. Experimental results demonstrate a light-to-light conversion efficiency of over 77% in the main amplification stage, with an ASE suppression ratio greater than 60 dB. The amplified laser exhibits an output linewidth of 10.3 kHz and maintains exceptional beam quality, with an M<inline-formula><tex-math>$^{2}$</tex-math></inline-formula> factor of less than 1.3. These results highlight the effectiveness of the proposed design for high-power, narrow-linewidth laser applications.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970262","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892355","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}

However, conventional wavefront sensors, such as the Shack-Hartmann wavefront sensor (SHWS), are limited by reduced accuracy in detecting local distortions and sensitivity to non-uniform beam profiles. Additionally, beam profile information is crucial for such applications. This paper introduces a new methodology that utilizes an SHWS-like structure to overcome these limitations. By employing a physical constraint learning approach, the proposed method simultaneously provides highly accurate wavefront and beam profile data. We first develop a pretrained network using microlens array (MLA) simulation datasets. To implement a practical MLA-based measurement system, this pretrained network is further fine-tuned with datasets modulated by a spatial light modulator in the system setup. Experimental results demonstrate that the proposed network can reconstruct both beam profiles and wavefronts in real-time. Compared to traditional SHWS reconstruction techniques, our approach enhances computation speed by over 100 times, while also providing beam intensity profile information and increasing wavefront sensing accuracy by approximately fivefold.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10967538","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883451","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 TianQin space gravitational wave detection Program uses star tracker (STR) and a charge coupled device (CCD)/ quadrant photodiode (QPD) to complete the construction of a bidirectional satellite laser link to achieve high-precision laser acquisition and tracking control. In order to solve the problem of the initial acquisition uncertainty cone being too large, the coordinate transformation matrix principle is applied to complete the STR line-of-sight calibration, so as to reduce the size of the acquisition uncertainty cone. The probability density distribution function of the uncertainty cone and the size of the uncertainty cone were determined based on the Monte Carlo simulation method. The average scanning acquisition time simulation calculation is completed based on the spiral scanning principle. The simulation results show that the size of the acquisition uncertainty cone after STR line-of-sight calibration is reduced by 73.24% compared with the original acquisition uncertainty cone, and the scanning acquisition time is reduced by 92.8% compared with the original scanning acquisition time.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10965890","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937954","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}

ASD is a neurodevelopmental disorder that affects individuals throughout their lives, and its diagnosis allows access to treatments that improve their prognosis. Saliva analysis by Fourier Transform Infrared Spectroscopy (FTIR), which was not previously reported, appears to be a promising diagnostic tool for ASD. This study acquired spectra from samples of 19 ASD and 19 control children. Spectral signatures suggest the dominance of protein secondary structures, β-pleated sheet and α-helix structures in ASD and control children, respectively. Support Vector Machine (SVM) gave the best diagnosis, with sensitivity, precision, and specificity being 92%, 94%, and 95%, respectively. Shapley values analysis to understand the impact of spectral features on the SVM classifier identified β-pleated and β-turn sheets as responsible for classification.

Silicon-organic hybrid (SOH) modulators present a promising solution due to the favorable electro-optic coefficients and fast response times of EO organic materials. However, the waveguide's nature limits the effective interaction between photons and EO materials. Although this interaction can be enhanced by utilizing advanced structures such as slot waveguides and slow-light techniques, new challenges arise, including strong dispersion that compromises bandwidth. In this paper, we propose a novel low-dispersion, slow-light waveguide structure based on a coupled one-dimensional photonic crystal slot resonator waveguide (coupled 1D PC SROW). By cascading multiple coupled resonators, the structure creates a low-dispersion, slow-light region within the photonic bandgap. Combining the strong optical field confinement of the slot with the slow-light enhancement in the time domain, modulation efficiency, quantified by <italic>VπL, can be significantly improved. As an example, we demonstrate that a <italic>VπL of 0.57 Vmm can be achieved for a low-dispersion wavelength range of 2.55 nm. The improvement in modulation efficiency allows for a reduction in the phase shifter length to 119 μm, overcoming the bandwidth limitations imposed by spatial walk-off between the electrical and optical waves and enabling a bandwidth of 108 GHz, a value challenging for conventional approaches. This study presents a viable alternative for realizing compact, ultra-broadband, and energy-efficient optical modulators.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10964245","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888287","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}
