Abstract: PROBLEM TO BE SOLVED: To realize mutual connections having high performances, low losses and environmentally stable qualities in connection parts of optical fibers of an integrated circuit connected to a plurality of optical fibers by passive matchings. SOLUTION: An optical integrated circuit(OIC) 10 and an optical array 20 (these are written as the OIC, etc., in the following) are mounted on a planar bridge structure 30 to form a device capable of being connected to other devices easily. The OIC, etc., are consisting of silicone substrates 100, 200 including reference areas 14, 24 and a top part side including a plurality of optical paths 16, 50. The optical paths are positioned on respective reference areas with the interval of a correct distance. Etchings are applied and alignment features 13, 23 are included in substrates of bottom parts of the OIC, etc. The planar bridge structure us brought into contact with reference surfaces of the OIC, etc., and alignments in the longitudinal direction of optical paths are performed. When fibers of the array are properly selected, excellent alignments are realized. The entire structure of this circuit is made to be a single structure by placing a bridge substrate on the OIC and by attaching spring clips clipping all constituting substrates.

Abstract: PROBLEM TO BE SOLVED: To make convertible modes in an optical circuit network by operating laser beams by using spherical lenses disposed in an optical path having an optical link gap to excite a multimode in a multimode optical waveguide. SOLUTION: The mode converter 110 includes a first spherical or round lens 179 and a second spherical or round lens 183. The output face of a single mode waveguide 126 is positioned at the focus of a first spherical lens 179 which is at a distance f1 from the first spherical lens 179. Similarly, the input face 169 of a multimode waveguide 133 is positioned at the focus of a second spherical lens 183, which is at a distance f2 from the second spherical lens 183. The first and second spherical lenses 179 and 183 are disposed to form an optical link gap of length L between them. The length L is specified so that both of the output face 156 and the input face 169 are substantially positioned at the focuses of the first and second spherical lenses 179 and 183, respectively.
