摘要： PROBLEM TO BE SOLVED: To solve the problem in which a plane optical circuit component constituted by connecting end surfaces of a plurality of plane optical circuits increases in connection loss owing to optical axis deviation when plane optical circuits whose substrates curve in different directions are connected so as to have the substrates opposite each other. SOLUTION: When two plane optical circuits composed of optical waveguides formed on substrates are connected, connection end surfaces of the two plane optical circuits (110, 120) are formed so as to have the same tilt to the substrates (111, 121), substrates of adjacent plane optical circuits are made vertically opposite in position (direction) not to face each other, and the optical waveguides (112, 122) have their optical axes aligned with each other and are connected and fixed. This constitution facilitates machining of the connection end surfaces, enables plane optical circuits differing in substrate curving direction to be connected together, and secures setting of an ultraviolet-ray setting adhesive.

摘要： PROBLEM TO BE SOLVED: To heighten the degree of integration in a lattice type optical filter formed by alternately longitudinally connecting symmetrical Mach Zehnder interferometer circuits (symmetrical MZIs) and optical path length difference setting circuits of asymmetrical MZIs in a multistage shape.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized optical circuit which has sufficiently high efficiency even with a slow refractive index distribution (small refractive index level difference). SOLUTION: In an optical circuit design area 1-1, an input port 3-1 and output ports (a) and (b) are provided and a spatial refractive index distribution in a medium is found from a field distribution of propagated light and a field distribution of reversely propagated light so that phase differences between the propagated light and reversely propagated light at respective points are eliminated. This refractive index distribution is found by determining virtual two-dimensional meshes in the optical circuit design area 1-1 and determining refractive indexes of fine areas (pixels) demarcated with the meshes, pixel by pixel. With such a spatial refractive index distribution, an optical circuit is obtained which, for example, inputs light beams of 1.31 and 1.55 μm in wavelength from the input port 3-1 and outputs the light of 1.31 μm from the output port (a) and the light of 1.55 μm from the output port (b).
