Experimental demonstration of optical field evolution in waveguide junctions by using a video camera observing system.
We have experimentally proved the optical field evolution in waveguide junctions formed by potassium ion exchange in a glass substrate using a microcomputer assisted video camera observing system. The optical field profiles in various waveguide junctions such as Y- and X-junctions have been clearly observed. Most of the results support the predicted operation of the junctions.
