Although some infrared SPADs can operate at room temperature, thermoelectric coolers are still essential, increasing complexity (operation and device packaging) and power consumption. Passively-cooled SPADs could be realized by avalanche materials exhibiting better temperature stability. A promising candidate is the InGaAs/AlGaAsSb SPAD, because the AlGaAsSb multiplier is highly stable with temperature. In this work, we report single photon detection performance of InGaAs/AlGaAsSb SPADs at room temperature and 1550 nm wavelength using multiple devices for each type of measurements. With 0.1 photons per pulse and 15 μm diameter devices, the maximum SPDE was 14% at DCR of 30 Mc.s<sup>−1</sup>, respectively. The best NEP value is around an order of magnitude higher than InGaAs/InP SPADs, but are comparable to InGaAs/InAlAs SPADs. Within the relevant overbias range and repetition rate up to 1 MHz, the DCR was unaffected by afterpulsing. Timing jitters were as low as 150 ps, matching InGaAs/InP SPADs. The results of this work are much more competitive than the previous report of InGaAs/AlGaAsSb SPAD, which required cooling to 200 K to detect single photons. Further research could help InGaAs/AlGaAsSb SPADs progressing towards passively-cooled single photon detectors for room temperature operation.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10884001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512877","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, severe performance limitations, including line-of-sight dependency, signal attenuation caused by obstacles, and restricted coverage, present a major challenge for the development of VLP. This article constructs an LED array-based hybrid indoor positioning system. An innovative LED array beacon is developed to simultaneously transmit coordinate and graphical information. A hybrid receiving structure, comprising an image sensor (IS) and a photodetector (PD), is constructed along with a dedicated hybrid positioning algorithm. This algorithm leverages image processing techniques to track the target trajectory, converts light intensity to identify the identification of LED, which finally resolves the target's precise world coordinates. The system's performance was validated through three experimental trials. The results demonstrate that the proposed beacon effectively covers the entire positioning area, achieving an average positioning error of 8.32 cm and a maximum positioning distance of 6.8 m. These results suggest that the proposed system provides a robust and efficient solution for precise indoor positioning applications in next-generation wireless communication networks.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-11"},"PeriodicalIF":2.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10886945","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455329","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 scheme solely necessitates vector length calculation via addition and subtraction operations and obviates the necessity of employing a direct digital synthesis (DDS) module, in contrast to conventional ABC schemes. By this means, the proposed scheme demonstrates reduced algorithmic complexity and a faster convergence rate, requiring only 0.3∼0.5 s to track and lock from a random bias point to a linear bias point, about 30 times faster than current commercial products. Moreover, unlike the commonly used single-tone dither signal (STDS), the PRBS-based dither signal in this scheme is broadband and has lower power spectral density and peak power at the same power level. Therefore, it not only induces lower nonlinear distortion in the transmitted signal but also has strong noise resistance, contributing to good control accuracy and robustness. The performance of DVMM-based ABC and STDS-based ABC is evaluated in 40/20 Gbaud 16/64 QAM coherent optical transmission systems, showing that DVMM can effectively reduce the bit error rate (BER) and has superior transmission performance.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-5"},"PeriodicalIF":2.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10882879","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518846","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}

Using the finite element numerical analysis method, we analyze the changes of the temperature field distribution within the crystal and demonstrate the effectiveness of the “quasi-rotating” cooling system in thermal management. The results show that the “quasi-rotating” frequency and pump power have a more significant influence on the thermal lens effect than the cooling water temperature. Compared to previous studies, our new method accurately predicts the thermal focal length of the moving crystal and provides direct guidance for resonator design, as shown in this paper. These findings provide a theoretical foundation for the design and enhancement of high-power solid-state lasers.

By mapping the echo signal into optical domain, the time-frequency characteristic is re-constructed through stimulated Brillouin scattering (SBS), realizing the selective suppression on high-power optical signal mapped by the interference. Based on this concept, a MWP TFL system based on the optical spectrum processing is constructed, and proof-of-concept experiments are demonstrated to verify the feasibility of the proposed strategy under different interference scenarios. Employing the proposed MWP TFL, the signal-to-noise ratio of the detection results, which is severely degraded by asynchronous interference, can be improved by 27.97 dB, and the suppression ratio on the false targets generated by the synchronous interference can reach 34.10 dB. The experimental results shows that the strategy can further enhance the survivability of multiband radar without compromising the range resolution for target detection. In addition, experiments are carried out to demonstrate the capability of the proposed strategy under different interference-to-signal ratios, showing a good adaptability to the complex interference scenarios.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10870138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430457","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}

By introducing the TSW structure into the DC-PBF, the loss of the secondary eigenstate of polarization (ESOP) mode is significantly increased through the strong mode coupling with the higher-order TE/TM mode of the TSW. Thus, the SP performance is achieved through the significantly high loss of the secondary ESOP mode in conjunction with the relatively low loss of the primary ESOP mode. In order to design ultralow IL and ultrahigh PER SP couplers based on DC-PBF with TSW, the low-loss SP DC-PBF with TSW is established by considering the impacts of structure parameters and wavelength on both loss and coupling performance. Furthermore, the dependences of powers, coupling ratio, and PER in x(y)-polarization in two cores with different lengths are analyzed for the SP coupler based on DC-PBF with TSW. Finally, three ultralow IL and ultrahigh PER 3 dB SP couplers based on DC-PBF with TSW are designed through theoretical calculation of fabrication tolerance and operation bandwidth. These couplers exhibit narrow-band high PER (∼ 27.2 dB), short-length ultralow IL (∼ 0.00054 dB), and long-length ultrahigh PER (∼ 61.88 dB), respectively. The proposed ultralow IL and ultrahigh PER SP couplers based on DC-PBF with TSW have potential applications in high-precision resonant PBF optic gyroscopes as well as other PBF applications.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10870402","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455151","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 solve this problem, we propose an inverted packaging structure for LED display devices. The LED chips’ emitting surface is mounted on the transparent carrier board (TCB) while the backside is packaged by the composite encapsulation, causing that the substrate is inverted to the topside of devices. As a result, the chips can emit light directly from the TCB and avoid the absorption loss of the encapsulation, leading to the high ACR and LOE performances. Compared to traditional devices, the inverted device showed an average increase of over 800% in luminous flux (LF) and LOE, and an average increase of over 390% in ACR. Additionally, the devices exhibited excellent soldering performance, corrosion resistance, airtightness, and thermal stability. This novel device overcomes the bottleneck of achieving both high ACR and high LOE, providing new insights for the development of LED display technology.
