| The paper presents a measuring stand which permits to determine the attenuation and modal birefringence of planar waveguide structures. The light is introduced into the waveguide through a prismatic coupler. This permits to determine attenuations of the subsequent modes. Mounting the polarizer in front of the lens of the camera it becomes possible to determine on the same test stand the modal birefringence of orthogonal pair of modes of the same order. |
