POFs are doped by immersing the fiber in the aqueous solution dissolved with RhB at elevated temperatures so that RhB molecules diffuse into the fiber. It is found that most RhB molecules are in the cladding. That is, only the fiber cladding is doped by RhB. The doping process involves no physical modification to POFs, thus the sensor fabrication process is facile and mechanical properties of POFs are not impacted. Two major factors that influence the angle sensing performance of the sensor are investigated, namely, the bending radius and the fiber diameter. Along with experimental study, ray-tracing simulation is also conducted to investigate their influence. Bending radius of 1, 2, 3 mm and two POFs in diameter of 250 and 500 μm are tested. In addition, POFs with different doping concentrations are fabricated and tested to examine its influence on the sensitivity. Among all fabricated sensors and various sensing conditions, the highest angle sensitivity of 0.0519 dB/° is achieved by the doped POF in diameter of 500 μm for the bending radius of 1 mm. It isn’t the highest among similar technologies, but easy fabrication process and embedding would make it attractive for practical angle sensing applications.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"99 ","pages":"Article 104584"},"PeriodicalIF":2.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146190825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hybrid RF/FSO links have the potential to increase bandwidths and reliability significantly, but most of the currently available routing schemes for FANETs assess problems of congestion control, optical path management, and security separately. We introduce SCA-OSF (Secure and Congestion-Aware Optical Switching Framework) for the introduction of software-defined optical control, which establishes light paths dynamically; congestion-aware multi-metric routing algorithms that consider the residual capacity, propagation delay, and optical link quality; and a lightweight trust-aware encryption layer that safeguards against unwanted behavior with minimal computational cost. This architecture shall be implemented in a Python-based simulator that also incorporates UAV mobility, optical fading, atmospheric attenuation, RF fallback behavior, and trust-driven path pruning. In keeping with such simulation experiments performed over multiple randomized runs having confidence-based averaging, SCA-OSF outperformed GPSR, AODV, OSPF-TE, HFAR, and SDN-OCP in terms of significantly high throughput, low latency, reduced congestion probability, and improved packet delivery ratio. SCA-OSF presents a scalable optical networking solution that is also resilient to congestion and aware of security, therefore falling under the scope of Optical Fiber Technology concerning advanced optical switching and emerging architectures of optical-wireless networks.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"99 ","pages":"Article 104582"},"PeriodicalIF":2.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146190824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional time-domain CDC (TD-CDC) requires lengthy filters, while frequency-domain CDC (FD-CDC) introduces latency and integration issues. Although hard-decision tap-clustered scheme reduces the TD-CDC complexity, its benefit diminishes over very long links where tap coefficients disperse widely. To address this, we propose a novel two-stage fuzzy-clustered TD-CDC scheme. It employs a soft-decision strategy, allowing filter taps to partially belong to two nearest neighboring clusters. Simulation results for 32 GBaud under 3200 km fiber length demonstrate 45% and 15% complexity reductions compared to clustered TD-CDC and FD-CDC, respectively, at the 6.7% HD-FEC threshold. Furthermore, across various baud rates and fiber lengths, the fuzzy-clustered TD-CDC scheme reduces complexity compared to clustered TD-CDC without compromising performance. Experimental validation on a 20 GBaud, single-polarization 16QAM standard single-mode fiber communication system over 1800 km demonstrates 53.8% and 40% complexity reductions compared to clustered TD-CDC and FD-CDC, respectively, at the 20% HD-FEC threshold.
