摘要： An optical multiplexer/demultiplexer includes first and second directional coupling portions in which first and second optical waveguides are provided to transfer a light between the first and second optical waveguides. Lengths of the first and second optical waveguides have a difference (nullL). A product between the difference (nullL) and a refractive index (n) of the first and second optical waveguides approximates a product between a cross-propagation wavelength (null2) and a value (Nnull) substantially equal to an integer (N), and a product between a through-propagation wavelength (null1) and the value (Nnull)null0.5. Power coupling ratio differences are at least approximately 1% and at most approximately 10%. Third power coupling ratios with respect to an average wavelength of the cross-propagation wavelength (null2) and the through-propagation wavelength (null1) are at least approximately 45% and at most approximately 55%.

These plural optical waveguide circuit chips (7(7A, 7B, 7C)) are connected to each other via an optical fiber (2). A temperature control means (5(5A, 5B, 5C)) is provided in each of the optical waveguide circuit chips (7(7A, 7B, 7C)), and the temperature control means controls a temperature of each of the optical waveguide circuit chips so as to adjust an optical transmission center wavelength of the corresponding optical multiplexing/demultiplexing circuit (8(8A, 8B, 8C)).

摘要： An optical device capable of optically coupling an optical element to be mounted to an optical waveguide circuit with low transmission losses is provided. On a base (20) provided with a substrate (1), a positioning pattern (15) made of a Pt film, a high melting point material having a melting point higher than a temperature of consolidating glass, is formed. Then, glass layers are formed by depositing glass particles by flame hydrolysis deposition and consolidating the deposited glass particles. The glass layers cover the top of the positioning pattern (15) and the base (20). The glass layers on the top and the periphery of the positioning pattern (15) are removed to expose the positioning pattern (15) and the base (20) therearound. The exposed area is to be a optical element mounting face 4. The positioning pattern (15) allows a light receiving device (8) to be positioned and fixed on the optical element mounting face 4 accurately. The light receiving device (8) is allowed to be coupled to a circuit of an optical waveguide forming area (2) formed in the remaining glass layers that have not been removed.
