What is a FBG / Fiber Bragg Grating?

FBG (Fiber Bragg Grating) is a device with a periodic grid structure embedded within an optical fiber, which reflects light at specific wavelengths. As the wavelength of light passing through the fiber changes, the reflected wavelength from the grating also shifts. This property allows FBG to be used to measure physical changes such as temperature, stress, and strain. FBGs are widely used in communication systems, sensor technologies, and structural monitoring. Their application as highly sensitive temperature sensors and strain gauges has gained particular attention.

Application of FBG / Fiber Bragg Grating

✅Temperature sensors
FBGs are capable of highly precise temperature measurements and are used in environments sensitive to temperature changes.
✅Structural monitoring
They are used in structures such as bridges and buildings to monitor strain and stress.
✅Communication systems
In optical communication systems, FBGs can be used for wavelength-selective signal processing and filtering.
✅Aerospace industry
FBGs are used in the structural monitoring of aircraft and for temperature and stress monitoring in spacecraft.
