摘要： PROBLEM TO BE SOLVED: To correctly multiplex or demultiplex light by reducing displacement of a grating spacing of a diffraction grating caused by a temperature change so as to reduce the variations in the diffraction angle of the light. SOLUTION: The diffraction grating 14 is held by fixing one of its side faces with a holder 15, and the holder 15 is supported and fixed on a substrate 11 with a support portion 16, in such a way that the diffraction grating 14 held with the holder 15 is in a state where it does not come into contact with the substrate 11. Accordingly, the diffraction grating 14 is fixed to the support portion 16 only on one side face via the holder 15, and furthermore, the diffraction grating 14 does not come into contact with the substrate 11. Consequently, although the lower section of the supporting portion 16 is displaced by the heat of the substrate 11, because the holder 15 is interposed between the displaced section and the diffraction grating 14, displacement of the support portion 16 does not directly affect the diffraction grating 14.

摘要翻译：要解决的问题：通过减少由温度变化引起的衍射光栅的光栅间隔的位移来正确地复用或解复用光，以便减少光的衍射角的变化。解决方案：衍射光栅14通过用保持器15固定其侧面之一来保持，并且保持器15以支撑部分16支撑并固定在基板11上，使得衍射光栅14 夹持器15处于不与基板11接触的状态。因此，衍射光栅14仅通过保持器15固定在一个侧面上的支撑部16上，此外，衍射光栅因此，虽然支撑部16的下部由于基板11的热量而发生位移，但是由于保持器15插入到位移部和衍射光栅14之间，所以位移支撑部分16不直接影响衍射光栅14.版权所有：（C）2010，JPO＆INPIT
