摘要： A light-shielding portion (10) shields the light spot of output light output toward a shunt position α by a projecting portion (12). Hence, the output light output toward the shunt position α does not travel to an output port (111). This allows to prevent crosstalk.

摘要： One side surface of a diffraction grating is securely held by a holder, and further, the holder is securely supported on a substrate by a supporter in such a manner that the diffraction grating held by the holder is not brought into contact with the substrate. In this manner, the diffraction grating is fixed only onto one side surface to the supporter via the holder, and further, the diffraction grating is not brought into contact with the substrate. Therefore, the lower portion of the supporter is displaced by heat generated in the substrate, however, the displacement of the supporter cannot adversely influence directly on the diffraction grating since the holder is interposed between the displaced portion and the diffraction grating.
摘要翻译： 衍射光栅的一个侧表面由保持器牢固地保持，此外，保持器以保持器所保持的衍射光栅不与基板接触的方式由支撑件牢固地支撑在基板上。 以这种方式，衍射光栅仅通过保持器固定在支撑体的一个侧表面上，此外，衍射光栅不与基板接触。 因此，支撑体的下部由于在基板中产生的热量而发生位移，但是由于保持器插入位移部和衍射光栅之间，所以支撑体的位移不会对衍射光栅直接产生不利影响。
