WebMoreover, the shorter the grating with a fixed period we used, the smoother dispersion profile that can be achieved. The analysis shows that an increase in the FBG number (within the same fiber length) leads to better compression, a reduced number of sidebands, and a higher power concentration in the pulse. WebThe dispersion D of the grating is defined as: “The angular separation Δθ per unit wavelength Δλ is called the dispersion D of the grating.” D = Δθ/Δλ For lines of nearly …
