WebThe grating equation is a good starting point when describing the properties of gratings. The grating equation can be written: sinα + sinβ m = -mλ/d where: α is the angle of incidence βm is the angle of diffraction. The angles are positive if they are directed counter clockwise, otherwise negative. WebThe grating period is set by Eq. (2.4.11) —after changing the minus sign to a plus sign because of the backward propagation of the dropped channel—and is a fraction of the wavelength of that channel. Fabrication of a Bragg grating in the coupling region between the two cores allows the same add–drop functionality [98].
