By utilizing an electro-optic comb generator that can adjust the repetition rate and central wavelength, this system generates numerous wavelengths from a single laser, serving as individual laser sources for spectral beam combining. Additionally, the system can incorporate a single line-broadener for all channels together for suppressing stimulated Brillouin scattering (SBS). A de-multiplexer is used to separate distinct wavelengths into individual fiber ports. By employing external phase modulation with white noise, the system can adjust the linewidth from a single frequency to 4 GHz. Furthermore, superior SBS control is achieved by tailoring the lineshape in the de-multiplexer, which reduces feedback-assisted SBS. With the customized lineshape, the SBS threshold of the system increases by <inline-formula><tex-math>$>$</tex-math></inline-formula>50%. By mitigating the complexities of conventional spectral beam combining, such as the use of multiple laser sources and the requirement for each laser to have a current and temperature controller, in addition to a line broadener, this innovative approach presents a cost-effective and less complex alternative for power scaling.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974512","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896456","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}

To study the impact of turbulence intensity on secret key extraction rate in atmospheric optical channels, this paper conducted a bi-directional synchronous atmospheric channel laser transmission experiment, analyzed the experimental data from three different time periods, and tested the Kolmogorov-Smirnov (KS) fitting efficiency values for five types of probability distribution normalized received signals. Comparative analysis shows that Johnson SB and Log-Normal distributions have the most ideal fitting effects on data. Based on these distribution parameters, a theoretical model of key capacity was constructed. The Monte Carlo method was used to simulate the secret key extraction rates under different turbulence intensities and different probability distribution models. The analysis results show that under weak turbulence conditions, using Johnson SB distribution yields about 87% higher average maximum secret key extraction rate than using Log-Normal distribution; under medium turbulence conditions, there is no significant difference in secret key extraction rates between the two distribution models. Compared with Log-Normal distribution, Johnson SB distribution is more suitable for secret key extraction under medium to weak turbulence intensities.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10971212","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125648","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 proposed structure consists of a gain ridge waveguide and an electrically insulated lossy ridge waveguide, enabling flexible control of transverse modes through the coupling effect between the fundamental mode of the lossy waveguide and the first-order mode of the gain waveguide. By optimizing key parameters—ridge waveguide width, spacing, and etching depth—the ACC forms a new optical mode distribution that suppresses higher-order modes through significant optical loss in the lossy section while the fundamental mode remains confined to the gain waveguide. The newly defined variables—the optical field proportion factor and the modal regulation factor—quantify the loss characteristics of higher-order modes.

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.

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}
