ABSTRACT:
As the wavelength conversion element is built by jointing a first clad member having a groove section filled with organic non-linear optical material and a second clad member, the core diameter can be controlled precisely and the clad diameter can be made larger easily. Also, as electrodes for applying voltage are arranged adjacent to both side areas along the groove section, the crystal orientation and refractive index can easily be controlled. In addition, the groove section is formed so as to leave both side faces of the first clad member, so that degradation of the organic non-linear optical material filled in the core as well as degradation of the coupling efficiency can be prevented.
