The coordinates of the unit constituent region (R11) are (X1, Y1), and the coordinates of the unit constituent region (Rmn) are (Xm, Yn) (m and n are natural numbers). The angle of rotation (&phgr;) of the vertex of an isosceles triangle with respect to the barycenter differs depending on coordinates, and there are at least three different angles of rotation (&phgr;) included in the entire photonic crystal layer. |
