1625nm Chirped Fiber Bragg Gratings

The grating period of chirped FBG is axial-variable instead of a constant. Because of this, the light with different wavelength will form optical path difference when reflected by chirped FBG. This feature of chirped FBG can be used to realize dispersion compensation of different wavelength signal in remote fiber-optical communication efficiently

What is Chirped Fiber Bragg Gratings?

The refractive index profile of the grating may be modified to add other features, such as a linear variation in the grating period, called a chirp. The reflected wavelength changes with the grating period, broadening the reflected spectrum. A grating possessing a chirp has the property of adding dispersion—namely, different wavelengths reflected from the grating will be subject to different delays. This property has been used in the development of phased-array antenna systems and polarization mode dispersion compensation, as well.
