Special Issue Information

Dear Colleagues,

Optical sensing and detection technology is widely used in environmental monitoring, energy exploration, autonomous driving, biomedicine and other fields, such as coherent laser detection, laser spectrum measurement and fiber optic distributed sensing. Lasers and optical sensors are the signal emitting and sensing units of optical sensing systems. The continuous breakthroughs in the mechanism, structure and performance of these photonic devices directly promote the progress of existing optical sensing technologies, further promoting the emergence of new optical sensing technologies and new application fields. For example, optimizing the linewidth and noise of lasers can significantly improve the frequency shift measurement accuracy of the Brillouin optical time domain reflectometer. The high-temperature- and radiation-resistant optical fiber sensors can be used for sensing applications in aerospace vehicles, nuclear reactors and other environments. The mid-infrared fiber gratings are the key components of mid-infrared all-fiber lasers, which can be applied to the fields of high-sensitivity gas detection.

This Special Issue aims to provide a platform for discussing the latest challenges, developments and applications of photonic devices such as lasers and sensors for optical sensing. Therefore, this Special Issue welcomes scholars from relevant research fields to submit high-quality original articles and reviews.

The theme of this issue is but not limited to the following:

  • High-coherence laser and its application in coherent laser detection;
  • Tunable laser and its application in laser sensing;
  • Optical fiber photonic device and its application in optical sensing;
  • New optical sensors for extreme environments;
  • Silicon-based sensors and their hybrid integration with semiconductor lasers;
  • Preparation and sensing application of mid-infrared fiber gratings.

Optical sensors constitute attractive alternatives to resistive probes for the sensing and monitoring of temperature (T). In this work, we investigated, in the range from 2 to 300 K, the thermal behavior of Yb2+ ion photoluminescence (PL) in glass hosts for cryogenic thermometry. To that end, two kinds of Yb2+-doped preforms, with aluminosilicate and aluminophosphosilicate core glasses, were made using the modified chemical vapor deposition (MCVD) technique. The obtained preforms were then elongated, at about 2000 °C, to canes with an Yb2+-doped core of about 500 µm. Under UV excitation and independently of the core composition, all samples of preforms and their corresponding canes presented a wide visible emission band attributed to Yb2+ ions. Furthermore, PL kinetics measurements, recorded at two emission wavelengths (502 and 582 nm) under 355 nm pulsed excitation, showed an increase, at very low T, followed by a decrease in lifetime until room temperature (RT). A modified two-level model was proposed to interpret such a decay time dependence versus T. Based on the fit of lifetime data with this model, the absolute (Sa) and relative (Sr) sensitivities were determined for each sample. For both the preform and its corresponding cane, the aluminophosphosilicate glass composition featured the highest performances in the cryogenic domain, with values exceeding 28.3 µsK−1 and 94.4% K−1 at 30 K for Sa and Sr, respectively. The aluminophosphosilicate preform also exhibited the wider T operating range of 10–300 K. Our results show that Yb2+-doped silicate glasses are promising sensing materials for optical thermometry applications in the cryogenic domain. Full article
