Fiber Bragg Grating Applications

1. Sensing applications (FBG sensors)

One of the basic fields of fiber Bragg grating applications is measurements, controlling parameters of the environment, such as temperature, pressure, strain, vibration, inclination, load and displacement. This technology gives an ability to provide monitoring across extended zones, fast response time and unique tracking opportunities.

Please find the below mentioned FBG solutions for various industries.

2. Lasers

Fiber Bragg gratings can be used as High Reflector (HR) and Output Coupler (OC) mirrors in cavities of fiber lasers. FBGs are also used to make semiconductor lasers single-frequency.

3. Telecommunications

In communications, fiber Bragg grating technologies are widely used in WDM systems, as filters and add/drop elements. Another FBG application is a dispersion compensator, because of its high precision and high adjacent channel interference rejection.
