The modulated laser period is set as an integer multiple of cavity delay to approach Fourier domain mode-locking, simultaneously boosting signals across frequencies and times.

This article constructs a processing prediction model for large-diameter ring pendulum double-sided polishing equipment. Based on this, a simulation of the theoretical removal amount distribution of ring-pendulum double sided polishing was conducted to ascertain the relationship between various process parameters and their impact on the surface removal amount distribution of the component. Based on the obtained relationship, a decision support system for the process parameters of ring-pendulum double sided polishing was developed, which achieved the deterministic removal of rings in medium and large aperture planar optical components and reduced the dependence of ring pendulum double-sided polishing on the personal experience of process decision-makers. After experimental verification, the characteristics of the simulation results of the processing prediction model were consistent with the actual processing results. The developed process parameter decision assistance system was used to make process parameter decisions for two 430 * 430 mm fused quartz components, achieving the removal of the target ring of the components. The surface figure accuracy of the two components has been processed from 3.09λ and 3.5λ to 1.53λ and 1.79λ, respectively.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 1","pages":"1-17"},"PeriodicalIF":2.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10850762","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361030","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 model is applicable over a wide temperature range from ambient down to cryogenic temperatures. A qualitative agreement is found between simulations and experiments.

Our device is designed for an etch-free III-V (InP) based stack, where lateral confinement of the hybrid mode is ensured by a thin gold (Au) strip on a thin indium tin oxide (ITO) strip. We optimize the waveguide geometry to produce maximum sensitivity while having compensable loss. Our investigation centers on three laser characteristics that are affected by the sensing fluid and that could serve as measurands: lasing wavelength, threshold current, and power-current slope efficiency. We determine the sensitivity of each measurand, assess the potential noise sources, and the limit of detection (LoD) associated with them.

All-optical frequency conversion gives flexibility due to the feasible high-speed reconfiguration in broad bands and large radio signal bandwidth. Optical frequency combs, featuring a spectrum of discrete, equally spaced coherent frequency lines, are crucial for high-precision metrology, spectroscopy, and telecommunications. Their effectiveness in all-optical frequency conversion depends on their stability in terms of frequency drift, phase noise, and power distribution across the comb lines. This paper evaluates experimentally the generation of optical frequency combs employing two distinct technologies: a dual-driven Mach-Zehnder modulator (DD-MZM) and an optomechanical crystal cavity (OMCC), and experimentally compares their performance for all-optical frequency conversion of 5G data streams. The DD-MZM implementation generates a comb with flexible line spacing and comprising several spectrum-flat lines with low phase noise (<inline-formula><tex-math>$-88.5$</tex-math></inline-formula> dBc/Hz at 1 kHz offset and <inline-formula><tex-math>$-108.3$</tex-math></inline-formula> dBc/Hz at 100 kHz offset). The OMCC implementation provides a reduced footprint (182 <inline-formula><tex-math>$mu mathrm{m}^{2}$</tex-math></inline-formula>) since it is implemented on a silicon chip and has the extra advantage of generating an optical comb without an external local oscillator, which reduces its power requirements (under 1 mW) while providing a phase noise of <inline-formula><tex-math>$-38.3$</tex-math></inline-formula> dBc/Hz at 1 kHz offset and <inline-formula><tex-math>$-97.1$</tex-math></inline-formula> dBc/Hz at 100 kHz offset. The polarization stability and jitter of both implementations are also evaluated. The experimental demonstration evaluates the error vector magnitude (EVM) of frequency-converted 3GPP 5G NR signals using both implementations, confirming the successful transmission with EVM smaller than 12.01% for DD-MZM up to the third harmonic and EVM smaller than 17.36% with the OMCC first harmonic.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 1","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10848171","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361031","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}

For robust delivery, accurate characterization of the pulse dispersion at the satellite locations without specialized equipment and its compensation is essential. This work demonstrates the delivery of dispersion-compensated pulses over standard optical fiber links and their characterization using a simple measurement module at satellite locations. The module uses a second-harmonic crystal and power detectors at the fundamental and second-harmonic wavelengths. A centrally located pulse shaper-based interferometer creates pulse pairs with varying time delays during the characterization phase. Together with the remote detectors, this provides the field and intensity autocorrelations, which describe the spectral and temporal domain of the pulse. We demonstrate our technique by transmitting dispersion compensated sub-400 fs pulses over two fiber optic links of 50 and 100 meters. The pulses are shaped adaptively before transmission to compensate for the dispersion-induced distortions. The pulse intensity and power spectrum are measured remotely and agree with those made at the source. This provides an easy distribution method for femtosecond lasers from central to satellite locations via standard optical fiber links on a time-share basis and their remote characterization.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 1","pages":"1-5"},"PeriodicalIF":2.1,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10841985","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106178","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 neuron states of the photonic reservoir are divided into distinct sections for different tasks by the designing of input matrix, and only a set of output weight matrix, applicable to all tasks, is ultimately trained. Therefore, MPRC is capable of handling multiple tasks simultaneously with a fixed set of parameters, mitigating the tedious process of hyperparameter optimization. The influence of neuron partition size and operating parameters on MPRC performance is studied systematically. Furthermore, the generalizability of MPRC is validated by performing four different tasks simultaneously.

This study introduces a Local Dimming (LD) method that employs LED backlight technology to enhance the edge quality of Liquid Crystal Display (LCD) photocuring 3D printing (LPP). LPP, known for its rapid and cost-effective fabrication, faces challenges with light leakage and precision under high-power ultraviolet (UV) light. By locally adjusting the backlight array's brightness to conform to the digital mask's shape, this study effectively suppresses LCD light leakage and improves edge definition. A comprehensive investigation into the LD method's process parameters—exposure time, pixel compensation coefficient, and initial backlight calculation—reveals significant improvements in print quality. The LD method achieves up to an 81.56% enhancement in dimensional accuracy compared to the conventional full-backlight technique. This research not only addresses the intrinsic light leakage in LCDs but also facilitates the high-resolution printing of complex structures, thus expanding the utility of LED devices in additive manufacturing.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 1","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10834600","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106176","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}
