    • An optical waveguide has first dielectric substance region which is formed on a surface of the crystalline silicon substrate, and has second dielectric substance region which is formed outside first dielectric substance region. First dielectric substance region is provided with a region in which a concentration of impurity elements for increasing and/or decreasing a refractive index in a direction of transmitting light is periodically increased and decreased, or provided with a corrugated structure, or wherein its width is periodically changed. Therefore, utilizing the property of thermal equilibrium, the optical waveguide has a grating which is thermally stable even at ordinary temperatures.
    • 光波导具有形成在晶体硅衬底的表面上的第一电介质区域,并且在第一电介质区域外部形成有第二电介质区域。 第一电介质区域设置有用于增加和/或减小透光方向上的折射率的杂质元素的浓度周期性地增加和减小的区域,或者设置有波纹结构,或者其宽度是周期性的 改变了 因此,利用热平衡的特性,光波导具有即使在普通温度下也是热稳定的光栅。
