Abstract: PURPOSE:To obtain the optical waveguide consisting of the uniform single crystal of an org. compd. having excellent nonlinearity by packing a soln. dissolved with the prescribed org. compd. into a hollow part to form a core enclosed with a clad and gradually cooling the entire part in the state of immersing the end face of the clad in the soln. CONSTITUTION:The soln. prepd. by dissolving the org. compd. which is a nonlinear optical material into a solvent is packed into the space to form the core enclosed by a clad layer and the entire part of the clad layer and the soln. are gradually cooled down to the temp. at which the soln. attains the supersatd. state in the state of immersing the end part of the clad layer into the soln. to grow the org. single crystal in the space to form the core. The optical waveguide consisting of the uniform single crystal is obtd. in this way even with the material, such as org. compd. having a large nonlinear optical constant, with which the single crystal is hardly obtainable by a melt solidification system.
