We have developed a novel method of numerical synthesis of optical waveguides, which consists of the endless loop of the random sampling of waveguide parameters, numerical analysis and the judgment of calculated result. This loop is repeated until some objective solutions satisfying required characteristics are discovered. When the structural condition is almost unknown and there is no clue to search it, this method is useful for discovering new-type waveguides, and this concept is applicable to any other devices. We applied this method to the search of new waveguide structures having multilayer claddings, and obtained many types of low loss single mode waveguides, including ARROW-type waveguides, waveguide-type polarizers and a very narrow band wavelength filter.
