Abstract: (2582 Views)
In this paper, we intend to use a two-prism coupling method in order to couple deuterium-halogen light in a flat waveguide, consisting of two clads with PVA polymer, and a core layer that the DR1 dye doped in PMMA polymer is in a guest-host system. 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.
