FBG - Bragg Grating Calculator


Fiber Bragg Grating Tutorial

figure:

When a Bragg grating exists in an optical fiber, it will reflect a specific wavelength dependent on the period of the Bragg grating and the index of refraction of the optical fiber. This calculator finds the period of Bragg grating needed for a predetermined wavelength and index of refraction.


Calculate Grating Period:
Bragg Wavelength: [nm]
Index of Refraction:

Period of Bragg Grating: [nm]
