摘要： The integrity of a solder jointing pad, which is used to mount an optical module, is enhanced by avoiding exposure to high temperatures used in the formation of an accompanying optical wave guide. The enhanced integrity of the solder jointing pad permits a mounting solder bump to be evenly distributed on the pad, which improves mounting position characteristics. The solder jointing pads are elongated in shape and arranged in parallel and perpendicular orientation with respect to an optical transmission path in the optical module. The enhanced integrity of the solder jointing pads permits a precise amount of solder to be introduced to the pads when mounting the optical module. The optical module can then be precisely positioned simply by varying the amount of solder introduced to the solder jointing pads. The optical device can be positioned with high accuracy by taking advantage of the self-alignment action which occurs between the molten solder bumps and the solder jointing pads. The optical module can thus be precisely positioned during manufacturing, without the need for additional adjustments.

摘要： In an optical coupling device for optically coupling an optical fiber to an optical waveguide formed on a crystalline substrate, the optical fiber is placed in a V-shaped groove formed on the substrate by anisotropic etching. The V-shaped groove is not linearly continuous, but intermittent to intermittently support the optical fiber. The intermittence of the V-shaped groove decreases undesired width expansion of the V-shaped groove. For this structure, a light axis alignment between the optical fiber and the optical waveguide is enhanced.

摘要： In a waveguide-type optical device, two optical waveguides are formed in a substrate of LiNbO.sub.3 or LiTaO.sub.3. On the substrate and the two waveguides, a blocking layer is formed to block a diffusion of Li ions from the substrate. On the blocking layer, a buffer layer made from SiO.sub.2 is formed. Each of the electrodes, from which operation voltages are supplied, covers each coupling part of the two optical waveguides, respectively, via the blocking layer and the buffer layer.

摘要： If a user pushes an operating member 50 in a state in which a case 11 of an optical transceiver 1 is locked in a cage 2, a lever 22 is turned to the front of the optical transceiver 1. If the user pulls out the turned lever 22, a projection provided on an actuating piece 28 abuts a convex portion 35 so that an end of the actuating piece 28 projects below the case 11. If a plate spring portion 18 of the cage 2 is pressed and elastically displaced by the end of the actuating piece 28, a lock portion 17 of the case 11 comes off a locking hole 19 of the plate spring portion 18, and the optical transceiver 1 can be pulled out of the cage 2.

摘要： There is disclosed a waveguide-type wavelength multiplexing optical transmitter/receiver module which is composed of an optical demultiplexer having an optical waveguide substrate and a filter disposed on an optical waveguide substrate, a laser diode and a photodiode. On the optical waveguide substrate, a first optical waveguide and a second waveguide are formed. On a first end face of the optical waveguide substrate, there is a cross section in which these optical waveguides cross each other. On a second end face of the optical waveguide substrate, there is an optical fiber and ports for connecting the laser diode. The filter reflects light with a wavelength of &lgr;1 from the laser diode and allows light with a wavelength of &lgr;2 from the optical fiber to pass therethrough. The laser diode is so disposed that the location of a center axis is shifted in the direction of the first optical waveguide relative to a cross axis being normal to a first end face. The photodiode does not receive an unwanted light with a wavelength of &lgr;2 or so from the laser diode. The waveguide-type wavelength multiplexing optical trans-mitter/receiver module having excellent light receiving characteristics is realized.

摘要： An optical coupling circuit includes an optical waveguide having an optical waveguide forming layer having a lower clad layer, a core layer and an upper clad layer. An optical element is mounted on an optical element mounting portion formed by removing a portion of the optical waveguide forming layer. The optical coupling circuit optically couples an end face of the exposed thin waveguide and the optical element mounted on the optical element mounting portion. In such optical coupling circuit, at least one thin film is inserted in the optical waveguide forming layer, and, in the thin film, there is a part of said thin film removed at said optical element mounting portion. Mass-production of the optical coupling circuit and simplification of the fabrication process can be achieved. A reference plane in the height direction is stably formed in the wafer, and heat radiation or removing of the light emitting element can be performed.
