Special Issue Information

Dear Colleagues,

This Special Issue will concentrate on all aspects of fundamental and applied research related to the fiber optic laser and fiber optic sensor fields. All topics focusing on lasers built with doped fibers as gain media or simply using fibers to achieve special goals of lasing or laser light steering are welcome. Sensors made from fibers, fiber components, or simply with fibers as light transmitting media that have been designed to carry out certain measurements or to calibrate some physical, chemical, biological or other parameters are also welcome in this Special Issue. Papers focused on the design and experimental validation of fiber optic lasers or fiber optic sensors are additionally welcome. Novel topics and reviews focusing on outstanding advances in either fiber lasers or fiber sensors are invited by this Special Issue. Topics of interests include, but are not limited to:

  • Modeling and simulation of any advanced type of fiber optic lasers or fiber optic sensors;
  • Fabrication of fiber optic lasers or fiber optic sensors with novel methods;
  • Advanced fiber optic lasers with rare-earth doped fibers used;
  • Advanced fiber optic lasers incorporating nonlinearity;
  • Advanced continuous-wave or pulsed fiber optic lasers;
  • Super-narrow-linewidth fiber optic lasers with a linewidth of ~500 Hz or below;
  • Cost-effectiveness of fiber optic lasers or fiber-optic sensors;
  • Novel fiber optic sensors with various types of interferometers, such as Mach–Zehnder interferometers, Michelson interferometers, Fabry–Perot interferometers and others used;
  • Novel scheme or system structure of distributed fiber sensors;
  • Fiber optics lasers or fiber optic sensors for perimeter intrusion detection;
  • Fiber optic sensors for harsh environments and materials in extremes;
  • Novel interrogation methods for fiber optic sensors, such as Fiber Bragg Grating Sensors and others;
  • Fiber optic sensor system with new signal modulation or signal processing;
  • Fiber optic lasers or fiber optic sensors in scientific, industrial, space, biomedical and other applications;
  • Fiber optic lasers or fiber optic sensors using specialty optical fibers;
  • Fiber optics lasers or fiber optic sensors for perimeter intrusion detection;
  • Novel FBG-based biomedical, chemical or environmental sensors;
  • Applications of fiber optic sensors in the oil and gas industry, electric power systems, aerospace missions, transport, civil structure and other areas;

Deploying distributed fiber-optic sensor (DFOS) technology to gather environmental parameters over expansive areas is an essential monitoring strategy in the context of comprehensive searches for anomalous places. This study utilizes a single temperature measurement channel within a commercial Raman-based distributed temperature sensing (RDTS) interrogator and divides it into two separate, uncorrelated paths to enable spatial duplex temperature measurements. The distinction between temperature events corresponding to each path in the dual separate path (DSP) in RDTS can be achieved when temperature events are concurrently occurring in the DSP. Additionally, the RDTS–DSP solution may integrate free space optics (FSO) into its fiber path, which serves to enhance the user-friendliness, scalability, and cost-effectiveness of DFOS technology. An RDTS measurement channel can effectively function as a DSP, thus doubling the RDTS measurement pathway, and can be combined with FSO to significantly improve RDTS performance. Full article
