    • In an optical waveguide device according to the present invention, a multi-layer cladding which is formed by laminating one or more high refractive index layers having the refractive index higher than that of a core and one or more low refractive index layers having the refractive index lower than that of the core, is disposed on a substrate on which an optical waveguide is formed, and utilizing the structural birefringence of this multi-layer cladding, the polarization-dependence of the optical waveguide is increased. As a result, it becomes possible to provide the optical waveguide device having a simple optical waveguide structure for selectively attenuating one of polarization modes of a propagated light.
    • 在根据本发明的光波导器件中,通过层叠折射率高于芯的折射率的一个或多个高折射率层和具有折射率的一个或多个低折射率层形成的多层包层 低于芯的布置在其上形成有光波导的基板上,利用该多层包层的结构双折射,增加了光波导的偏振度依赖性。 结果,可以提供具有简单的光波导结构的光波导器件,用于选择性衰减传播光的偏振模式之一。
