Abstract
PURPOSE:To contrive to allow the titled optical waveguide to have a multifunction by forming a low refractive index part whose refractive index is lower than a substance of a peripheral layer, and also, whose refractive index in lower than a substance of a propagation layer, in a part of the peripheral layer, and allowing said part to have functions such as a conversion of wavelength and a branch of light due to a non-linear optical effect, a separation of light whose wavelength is different, a directional coupling, etc. CONSTITUTION:A low refractive index part 3a... whose refractive index is lower than a substance of a peripheral part 2, and also, whose refractive index is lower than a substance of a propagation layer 1 is formed in a part of the peripheral layer 2. Also, a shape of this low refractive index part 3a... is formed to shapes such as a (y) branch, an (m)X(n) branch, a tapered shape, a directional coupling shape, etc., and allowed to have functions such as a conversion of wavelength and a branch of light due to a non-linear optical effect, a separation of light whose wavelength is different, a directional coupling, etc. Accordingly, simultaneously with the wavelength conversion and the branch of light, the branch of an input light and a converted light, or the improvement of the coupling efficiency can be realized by one element. In such a way, a device having a multiple function is obtained.
