Thermal analysis confirms the system’s exceptional heat dissipation capabilities. Compared to traditional rotary disk lasers, this laser fully utilizes high thermal conductivity efficiency of water cooling and low absorption coefficient of the gain medium to reduce thermal stress. We introduce a novel “quasi-rotation” mechanism for the water-cooled rotary laser to resolve the issue of water pipe entanglement. To achieve this, we propose an eccentric rotation design that utilizes a single motor to deliver uniform, high-speed rotation with exceptional stability. Initial experiments demonstrate a maximum output power of 76.5 W, a slope efficiency of 58.2%, and a power conversion efficiency of 52.4%. Output power is primarily limited by the available pump power in our lab. We also analyze the impact of water temperature and rotation speed on output power. Both continuous and pulsed pumping experiments further validate the system’s robust thermal management. Overall, our results highlight the significant potential of “quasi-rotating” water-cooled laser technology to enhance the power output of solid-state lasers.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 7","pages":"429-432"},"PeriodicalIF":2.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The initial pixelated structure is carefully designed to enhance algorithm robustness of the optimization process, thereby improving efficiency and avoiding local optima. The experimental results show that the insertion loss of both TE0 and TM0 is lower than 1.5 dB within the wavelength range of 1480-1580 nm, while the beam splitting ratio between the two output ports remains above 75%. In addition, the fabrication tolerance of the device is examined to ensure low insertion loss and reflection loss.

This system multiplexes community antenna television /broadcasting satellite / communication satellite video signals with frequencies from 90 MHz to 2.1 GHz, converts them into optical signals, and transmits them from the broadcaster building to customer houses. In the FM-conversion system, dispersion compensating fibers (DCFs) are used to compensate for the chromatic dispersion generated in the transmission optical fiber. However, due to the risk of DCF depletion in the long term, it is necessary to consider alternative dispersion-compensation configuration. Therefore, we propose a chirped fiber Bragg grating (CFBG) dispersion-compensation configuration and conducted an FM-conversion long-distance- transmission experiment using this configuration and evaluated its applicability. We clarified that the carrier-to-noise ratio is improved by arranging CFBGs in front of the transmission fiber, compared with using DCFs.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 8","pages":"437-440"},"PeriodicalIF":2.3,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, issues like fiber link damage and hardware mismatches between transmitter and receiver hinder its advancement to higher speeds and longer distance. In this letter, we experimentally demonstrate chaotic secure communication of a 64 Gbit/s PAM-4 signal transmitted over 250km using a chaotic optoelectronic oscillator (OEO) system, achieving record-breaking capacity-distance products of 16000-Gbit/s•km in optical-domain encrypted chaotic secure communication using single-core SMF.

A multi-span dispersion-managed fiber link, along with decision-directed least-mean square (DD-LMS) algorithm, is employed to address amplitude distortion caused by the fiber, modulation, and synchronization mismatches. Furthermore, we also successfully demonstrated in a 110-km deployed commercial optical fiber in Chengdu, China, presenting a cost-effective approach to strengthening commercial optical network security.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 7","pages":"425-428"},"PeriodicalIF":2.3,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics of the MMF-TSCF-MMF structure, referred to as the MTSCM, are analyzed and simulated using the beam propagation method (BPM) both before and after the seven-core fiber (SCF) is tapered. Simulations indicate a fiber Mach-Zehnder interferometer (MZI) is formed within the structure. Both simulation and experimental results demonstrate that the MTSCM structure exhibits a stronger evanescent field and more surrounding core and cladding modes. A sensitivity of −760 pm/°C is achieved by using MTSCM structure sensor in temperature measurement, significantly higher than that of the MSCM structure sensor. The proposed sensor holds a great potential for marine environment detection.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 7","pages":"417-420"},"PeriodicalIF":2.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
