    • The present invention provides an optical waveguide which comprises a core 4 for incident light and a core 5 for outgoing light, wherein the width of the core 5 for outgoing light is more than 1.5 times that of the core 4 for incident light. This optical waveguide permits the multiplexing and/or demultiplexing of light rays even when the wavelengths thereof undergo changes within the range of about 10 nm. In addition, the present invention further provides an optical multiplexer-demultiplexer which comprises the combination of an optical waveguide serving as an optical path and a diffraction grating for demultiplexing and focusing light, wherein the absolute value of the difference between the refractive index (nTE) of the core layer of the optical waveguide in the direction parallel to the plane of the film and that (nTM) of the core layer thereof in the direction perpendicular to the plane of the film is not more than 0.007 at the wavelength used. This optical multiplexer-demultiplexer permits the control of the wavelength fluctuation observed for the outputted signal light dependent on the polarization direction of the incident signal light to not more than 5 nm by the reduction of the birefringence index of the core layer of the optical waveguide to a level of not more than 0.007.
    • 本发明提供一种光波导,其包括用于入射光的核心4和用于出射光的核心5,其中用于出射光的核心5的宽度大于入射光的核心4的宽度的1.5倍。 该光波导即使当其波长在约10nm的范围内变化时也允许光线的复用和/或解复用。 另外,本发明还提供了一种光复用器 - 解复用器,其包括用作光路的光波导和用于解复用和聚焦光的衍射光栅的组合,其中折射率(nTE) 在平行于膜平面的方向上的光波导的芯层的垂直于膜平面的方向上的芯层的(nTM)在所使用的波长处不大于0.007。 该光复用器 - 解复用器允许通过将光波导的芯层的双折射率降低到对应于入射信号光的偏振方向的输出信号光观察到的波长波动为不大于5nm 一级不超过0.007。
