Then, using a Nd:YVO4 laser, whose wavelength is near the dye-absorbing region of spectrum, is divided into two parts, making a grating from the interference of these two beams on the waveguide,( dual-beam interference) in the direction perpendicular to the waveguide And convert it to a waveguide Bragg Grating Filter.
