In a diffraction grating element 10, between a first medium 11 and a fourth medium 14, a second medium 12 and a third medium 13 are disposed alternately to form a diffraction grating. The light, which enters the diffraction grating from the first medium 11, is diffracted at the diffraction grating portion and output to a fourth medium 14. Or, the light, which enters the diffraction grating from the fourth medium 14, is diffracted at the diffraction grating portion and output to the first medium 11. The index of refraction n1-n4 of each medium satisfies a relational expression of "n3<n1<n2r n3<=n4<=n2" or "n3<=n1<=n2, n3<n4<n2".
Dans un élément d'un réseau de diffraction (10), entre un premier milieu (11) et un quatrième milieu (14), un deuxième milieu (12) et un troisième milieu (13) sont disposés en alternance de manière à constituer un réseau de diffraction. La lumière, qui pénètre dans le réseau de diffraction par le premier milieu (11), est diffractée dans le réseau de diffraction et ressort dans un quatrième milieu (14), ou encore la lumière, qui entre dans le réseau de diffraction par le quatrième milieu (14), est diffractée dans le réseau de diffraction et ressort dans le premier milieu (11). L'indice de réfraction n1-n4 de chaque milieu satisfait l'équation n3 < n1 < n2, n3<=n4<=n2 ou n3<=n1<=n2, n1 < n4 < n2.
