To gain a clearer understanding of internal stress distribution and vibration response within slopes, this paper proposes a monitoring method for the stability of deep soil in slopes based on local strain and continuous vibration optical fiber sensing technologies. Firstly, a fiber Bragg grating-optical fiber vibration sensor packaged by FRP (Fiber Reinforced Plastics) for local strain and continuous vibration monitoring was developed and its sensing performance was experimentally investigated, and then the sensor was applied to a slope to carry out slope stability monitoring. The research results show that the strain sensing coefficient and the flexural sensing coefficient are 1.24 pm/με and 2.07 pm/cm respectively, and the FBG-DVS sensor can effectively measure the displacement distribution of deep soil in slopes and the vibration information generated by the expansion of cracks.

CO exposure can cause severe health effects, ranging from neurological and cardiovascular symptoms at low levels to loss of consciousness and death at high or prolonged levels. Hence accurate and early detection of CO is essential for public health and environmental safety. To detect CO gas, this paper presents the design and performance analysis of palladium-based fiber optic surface plasmon resonance sensor. Palladium (Pd) readily adsorbs CO molecules and enables sensitive and selective signal transduction in sensor systems, making it an efficient biorecognition layer for CO detection. The sensor’s response is analyzed using finite element method, with an emphasis on important performance metrics such as resonance shift and modal loss. Grating and non-grating Pd biorecognition layers are demonstrated to compare the performance of sensors. Introducing a Pd grating enhanced the sensor’s sensitivity by approximately 12.7 %, increasing from 6300 nm/RIU in the non-grating configuration to 7100 nm RIU<sup>−1</sup> with 100 nm residual cladding, 30 nm air gap width and 20 gratings. This research also provides a first-principle study of CO adsorption on Pd surface by density functional theory to examine the specific adsorption behavior of analyte, which remains a major challenge in the field. Two surface geometries, i.e., (1 × 1) and (2 × 1), were investigated; resulting in the (2 × 1) structure exhibiting more desirable adsorption character. High sensitivity and efficiency are demonstrated by the suggested biosensor in the detection of CO for the development of ultrasensitive SPR sensors.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"94 ","pages":"Article 104375"},"PeriodicalIF":2.7,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144890321","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}

Using separate setups for C and L-bands increases design complexity and cost while using a single setup deteriorates the flatness of the output gain spectrum. This work presents the design and implementation of a flat gain ASE source that can operate in C-band and L-band separately or combined with only a single optical setup for all bands. The optical setup designs are first optimized in a simulation environment for the required length of Erbium Doped Fiber (EDF), the number of pump lasers, pump powers, and pump wavelengths. Then, an optical management board containing a multi-laser control driver and embedded software algorithm is developed to achieve flat gain and separate operation of C/L/C + L bands. With this management board, the lasers on the optical setup can be controlled and the output spectrum can be adjusted to the desired optical power and ripple without requiring any external components such as optical switches/optical filters. The developed ASE source offers bandwidths of 36 nm (1524–1560 nm), 44 nm (1560–1604 nm), and 80 nm (1524–1604) for the C, L, and C + L bands, respectively, while providing a constant output power of 30 mW and a 3 dB power ripple across all bands.

While conventional C-band provisioning is nearing its spectral saturation point, expanding into additional spectral bands such as L, S, and E bands provides an avenue for scalable capacity enhancement. However, utilization of these heterogeneous spectral resources necessitates efficient provisioning strategies. This paper proposes a capacity aware-resource provisioning technique that prioritizes spectral bands based on their spectral capacity, favoring the highest-capacity band during allocation unlike traditional provisioning methods in the literature which prioritize the C-band for resource provisioning which has least resource availability. Through comprehensive simulation-based evaluation, we show that band sequencing strategies can substantially affect the network performance. Simulations have been conducted on NSF and USNET topologies by considering the following performance metrics: request blocking probability (RBP), bandwidth blocking probability (BBP), spectral efficiency (SE), total bits transmitted, band utilization distribution (BUD) and band resource allocation time.

However, in long-distance or high-data-rate transmission scenarios, signal distortion caused by fiber nonlinear effects significantly degrades system performance. Traditional nonlinear compensation methods, such as the high-order Volterra series, can address some of these challenges but are limited by high computational complexity and insufficient accuracy, making them unsuitable for real-time transmission requirements. To address these challenges, we propose a convolutional neural network (CNN)-based nonlinear equalization method. By introducing a sliding window mechanism, the global signal is divided into local segments, enabling the model to efficiently capture local nonlinear features while maintaining low computational complexity. Additionally, CNNs leverage parameter sharing and parallel computation to significantly improve training and inference speeds, overcoming the computational inefficiencies and sequential nature of recurrent neural networks (e.g., Bi-LSTM) in handling time-series data. Simulation results demonstrate that, for a 16-QAM modulated PDM-WDM CO-OFDM system with a data rate of 850 Gb/s, the proposed method improves the maximum transmission distance by 100 % compared to the Volterra series model. Furthermore, while achieving comparable bit error rate (BER) performance to the Bi-LSTM model, the computational complexity of the CNN-based method is significantly decreased. The proposed CNN method exhibits superior robustness and performance in nonlinear equalization.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"94 ","pages":"Article 104359"},"PeriodicalIF":2.7,"publicationDate":"2025-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144858144","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}
