Special Issue Information
Dear Colleagues,
The research significance of new and advanced fiber gratings is profound. Traditional fiber Bragg gratings include uniform fiber Bragg gratings, chirped fiber Bragg gratings, phase-shifted fiber Bragg gratings, sampling fiber Bragg gratings, blazed fiber Bragg gratings, and long-period fiber Bragg gratings. These achieve the reflection, filtering, or dispersion compensation of optical signals through periodic refractive index modulation and are widely used in the fields of optical fiber communication and sensing.
New types of fiber Bragg gratings include spiral fiber Bragg gratings, tapered fiber Bragg gratings, multimode fiber Bragg gratings, micro-/nanostructured fiber Bragg gratings, and special fiber Bragg gratings (such as toe chirped fiber Bragg gratings, staggered fiber Bragg gratings, etc.). These new structures expand the functionality and application range of fiber Bragg gratings by optimizing refractive index distribution or introducing multidimensional modulation. For example, spiral fiber Bragg gratings can reduce polarization related losses, and multimode fiber Bragg gratings can solve temperature stress cross sensitivity problems.
The new fiber Bragg gratings can achieve high-density wavelength division multiplexing and dynamic dispersion compensation in communication. In sensing, temperature and stress can be independently demodulated through a multipeak structure, breaking through the limitations of cross sensitivity. Micro-/nanostructures can be utilized in imaging to enhance resolution; for example, multimode fiber Bragg gratings can achieve independent measurements of temperature and stress through multipeak structures, chirped fiber Bragg gratings compensate for dispersion in high-speed communication through gradient periods, spiral fiber Bragg gratings reduce polarization loss through three-dimensional refractive index modulation, and micro-/nanostructured fiber Bragg gratings can improve sensing sensitivity through nanoscale modulation.
With this broader context in mind, this Special Issue aims at presenting the latest developments in fiber Bragg gratings from basic theory to engineering applications, with a focus on manufacturing process innovation, new grating structures, and functional design. By analyzing their applications across a range of fields, the core value of fiber Bragg gratings in terms of improving monitoring accuracy, reducing operation and maintenance costs, and enhancing system reliability can be revealed, providing support for the large-scale application of fiber Bragg gratings in next-generation photonic devices and intelligent systems. Research areas of interest for this Special Issue include, but are not limited to, the following topics:
- Fiber Bragg Gratings;
- Femtosecond Laser Engraving;
- Multiparameter Sensing;
- Optical Communication;
- Industrial Internet of Things;
- Fiber Grating Devices;
