Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue dealing with the latest developments in optical fiber-based sensing technology. Optical fiber sensors have been rapidly developed due to their small size, excellent sensing performance, large bandwidth, free from electromagnetic interference, environmental ruggedness, and ease of manufacturing multiplexed or distributed sensors. Recent advances in optics and photonics, biochemistry, and biology have increased the utility and demand of optical fiber sensing devices in various fields including security and defense, transportation, point-of-care diagnostics, oil and gas industries, environmental monitoring, and food production. The aim of this Special Issue is to collect scientific contributions on optical fiber-based sensing devices for a wide range of applications, and to make significant progress in the design and fabrication of novel optical fiber sensors.

We invite researchers and scientists from academia and industry to contribute original research articles, letters, and reviews. The research areas for this special issue may include, but are not limited to, the following:

  • optical fiber sensors
  • surface plasmon resonance
  • photonic sensors
  • fiber Bragg gratings (FBGs)
  • long period gratings (LPGs)
  • interferometric optical fiber devices
  • fluorescent sensors
  • light diffuser-integrated sensors
  • evanescent wave sensors
  • fiber laser sensors

We look forward to receiving your contributions.

This paper outlines the successful utilization of deep learning (DL) techniques to elevate data quality for assessing Au-TFBG (tilted fiber Bragg grating) sensor performance. Our approach involves a well-structured DL-assisted framework integrating a hierarchical composite attention mechanism. In order to mitigate high variability in experimental data, we initially employ seasonal decomposition using moving averages (SDMA) statistical models to filter out redundant data points. Subsequently, sequential DL models extrapolate the normalized transmittance (Tn) vs. wavelength spectra, which showcases promising results through our SpecExLSTM model. Furthermore, we introduce the AttentiveSpecExLSTM model, integrating a composite attention mechanism to improve Tn sequence prediction accuracy. Evaluation metrics demonstrate its superior performance, including a root mean square error of 1.73 ± 0.05, a mean absolute error of 1.20 ± 0.04, and a symmetric mean absolute percentage error of 2.22 ± 0.05, among others. Additionally, our novel minima difference (Min. Dif.) metric achieves a value of 1.08 ± 0.46, quantifying wavelength for the global minima within the Tn sequence. The composite attention mechanism in the AttentiveSpecExLSTM adeptly captures both high-level and low-level dependencies, refining the model’s comprehension and guiding informed decisions. Hierarchical dot and additive attention within this model enable nuanced attention refinement across model layers; dot attention focuses on high-level dependencies, while additive attention fine-tunes its focus on low-level dependencies within the sequence. This innovative strategy enables accurate estimation of the spectral width (full-width half maxima) of the Tn curve, surpassing raw data’s capabilities. These findings significantly contribute to data quality enhancement and sensor performance analysis. Insights from this study hold promise for future sensor applications, enhancing sensitivity and accuracy by improving experimental data quality and sensor performance assessment. Full article
