Special Issue Information

Dear Colleagues,

The fiber grating sensor is one of the most important types of fiber sensors developed in the past three decades. As a kind of grating structure in optical fibers, fiber grating has its own unique advantages besides inheriting all the advantages of a fiber sensor, such as wavelength encoding of sensing information, high-precision localization detection, multiplexing capabilities, etc. Now, fiber grating sensors continue to flourish and their applications are expanding. New designs and discoveries have continued to drive technological developments.

This Special Issue will focus on all aspects of this active research field, aiming to reflect the development of fiber grating sensors in design, manufacturing and applications. Both original research papers and review papers are welcome. Technical topics include, but not limited to, the following:

  1. Fiber Bragg grating sensors;
  2. Long-period fiber grating sensors;
  3. Special structures (tilted, chiral, phase-shifted, etc.) of fiber grating sensors;
  4. New design and fabrication techniques of fiber grating sensors;
  5. Fiber grating sensors fabricated by femtosecond laser;
  6. Fiber grating sensor network and systems;
  7. Interrogation methods for fiber gratings;
  8. Fiber-grating-based temperature, strain, deformation, and bio-chemical sensors;
  9. Smart sensing systems using fiber grating sensors;
  10. Fiber grating sensors for wearable and medical applications;
  11. Fiber grating sensors for harsh environment applications;
  12. Packaging and long-term stability of fiber grating sensors.

Variations of seawater salinity often cause ocean internal waves, water masses and stratification, which affect the stability of the ocean environment. Therefore, the study of seawater salinity is significant for the prediction of changes in the ocean environment. However, existing methods for measuring seawater salinity generally have the disadvantages of low sensitivity and low accuracy. In this work, we proposed a seawater salinity sensor based on long period fiber grating (LPFG) in the dispersion turning point (DTP), which has demonstrated the possibility to fabricate LPFG with a shorter grating period by CO2 laser in a thin single mode fiber (SMF) of 80 μm cladding diameter without etching. For obtaining higher sensitivity that could meet the measurement requirement in practice, the proposed sensor was optimized by combining etching cladding and DTP. After the LPFG working near DTP was fabricated by a CO2 laser, the cladding diameter was reduced to 57.14 μm for making cladding mode LP1,7 work near DTP by hydrofluoric acid (HF) solutions. The experimental results have demonstrated that a sensitivity of 0.571 nm/‰ can be achieved when the salinity increases from 5.001‰ to 39.996‰, and the sensor shows good repeatability and stability. Based on its excellent performance, the optimized LPFG is a prospective sensor to monitor seawater salinity in real time. Meanwhile, a low-cost way was provided to make LPFG work near DTP instead of ultraviolet exposure and femtosecond laser writing. Full article
