Abstract
Observation of optical guidance in an epitaxial mixed‐crystal film (NH4)xK1−xH2PO4 grown on a (100) KDP substrate is reported. The film thickness was ∼38 μ. The ordinary and extraordinary indices of the film for x=0.07 at 589.3 nm were nfo=1.5105 and nfe=1.4695. The difference in corresponding indices between the film and the substrate was 10−3. When the film waveguide was excited by a Gaussian He–Ne laser beam, the distribution of energy across the output face of the crystal confirmed one‐dimensional guiding in the epitaxial film.Keywords
