METHOD OF MANUFACTURUNG A RIDGE-SHAPED THREE DIMENSIONAL WAVEGUIDE |
摘要 |
A method of manufacturing a ridge-shaped 3-dimensional waveguide, has the steps of: forming a crystal film made of a second ferroelectric oxide non-linear crystal having a refractive index higher than that of a substrate made of a first ferroelectric oxide non-linear crystal on the substrate; forming a metal film on the crystal film; forming a mask by etching the metal film; and forming a ridge portion by selectively removing the crystal film through the mask by a dry etching method.
