Fiber Bragg Gratings and Their Applications
Fiber Bragg gratings (FBGs) are widely used in telecommunications, sensing, and laser systems due to their ability to reflect specific wavelengths and respond to environmental changes.
Telecommunications
FBGs are extensively used in optical communication systems for dispersion compensation, wavelength filtering, and signal routing. They act as inline optical filters to block or reflect specific wavelengths, improving signal quality and enabling dense wavelength-division multiplexing (DWDM) in fiber networks .
Sensing Applications
FBGs serve as highly sensitive fiber-optic sensors for measuring strain, temperature, pressure, and vibration. They are widely applied in structural health monitoring (SHM) of bridges, buildings, and aerospace structures, as well as in environmental monitoring. Changes in the reflected Bragg wavelength correspond to variations in the measured physical parameters, allowing precise and real-time monitoring .
Laser Systems
In fiber lasers, FBGs function as wavelength-specific reflectors or mirrors in distributed Bragg reflector (DBR) and distributed feedback (DFB) lasers, enabling narrow-linewidth operation and stable laser output .
Medical and Biochemical Applications
FBGs are also used in biosensing and medical diagnostics, where they detect changes in refractive index or strain in biological samples. Their compact size and immunity to electromagnetic interference make them suitable for minimally invasive sensing and imaging applications .
Specialized Applications
- Chirped FBGs: Used for dispersion compensation and pulse shaping in high-speed optical networks.
- Apodized FBGs: Reduce spectral side lobes for improved filtering performance.
- Surface-relief FBGs: Operate at high temperatures for industrial sensing applications . FBGs are valued for their high sensitivity, compactness, and versatility, making them a critical technology across multiple fields, from telecommunications to structural and biomedical sensing .
