摘要： PROBLEM TO BE SOLVED: To provide a waveguide type optical circuit showing superior characteristics, even if a plurality of optical branching/coupling circuits are possessed, by configuring the optical circuit to suppress re-coupling of radiant light in the optical branching/coupling circuit of the poststage. SOLUTION: The waveguide type optical circuit has a waveguide structure composed of a lower clad, a core arranged on the upper face of the lower clad, and an upper clad covering the core, and includes at least a first and a second two optical branching/coupling circuits. The first and second optical branching/coupling circuits have a structure in which waveguide light and radiant light are coupled, wherein the input waveguide of the second optical branching/coupling circuit is connected to the output waveguide of the first optical branching/coupling circuit. The refractive index of the upper clad is made lower than that of the lower clad for the purpose of avoiding the re-coupling of the radiant light of the first optical branching/coupling circuit, through propagation in the lower clad, with the waveguide light in the second optical branching/coupling circuit.

摘要： PROBLEM TO BE SOLVED: To eliminate mirror angle errors within a wafer surface in a flat surface optical circuit with a micromirror manufactured by using a diagonal vapor deposition process. SOLUTION: In the flat surface optical circuit having a plurality of optical path changing mirrors within a substrate, a mirror surface direction (β) is so set that the prescribed mirror angle (δ) can be obtained based on the positional relations (D and θ) on the vapor deposition source and the substrate surface in a diagonal vapor deposition process. Namely, the respective mirror manufacturing positions (x and y) and mirror surface direction (β) are controlled by using prescribed formulas 1 and 2 in such a manner that the prescribed mirror angles (δ) (uniform within the substrate) can be obtained based on the positional relations between a vapor deposition source and the manufacturing positions (x and y) of the respective mirrors on the substrate in order to manufacture a plurality of the mirrors with good uniformity within the substrate using the diagonal vapor deposition process. The formulas 1 and 2 are similarly applicable in the case of using diagonal exposure in place of the diagonal vapor deposition. COPYRIGHT: (C)2005,JPO&NCIPI
