摘要： Embodiments of the present disclosure are directed to an optical assembly for optical transceiver which is composed of two separate sub-assemblies including an assembly that is coupled with a substrate and has a post formed to have a central hollow into a multi-branched shape, for increasing the optical alignment efficiency between the optical elements included in the optical assembly for optical transceiver which involves multiple complicated and sophisticated processes, the optical assembly for optical transceiver being structured to drain out the epoxy resin or the refractive index matching material used when coupling the optical fiber inserted from the outside with the optical elements, whereby greatly reducing optical alignment errors caused by the epoxy resin or refractive index matching material, as well as directed to an optical transceiver using the optical assembly for optical transceiver.

摘要： Embodiments according to the present disclosure relate to an optical transmitting device and an optical receiving device which can minimize the alignment error between the light source and the photodetector on the substrate, miniaturize the devices, and require no separate guide member reducing manufacturing costs, while satisfying the design requirements for sub-miniaturization, and performing optical transmission and reception more efficiently.

摘要： An optical transceiver device includes a baseplate including a set position for mounting an optical element, an alignment plate including a mounting unit, a first and a second reference hole. The device includes an optical-fiber fixing block configured to fixedly mount at least one of a lens unit and an optical fiber optically linked with the optical element and to include a first and a second post, and a housing for enclosing the optical-fiber fixing block and alignment plate. The second post is inserted into the second reference hole in a looser manner than inserting the first post into the first reference hole, and the set position is determined by a first baseline passing through the first and the second reference hole and by a second baseline intersecting with the first baseline and positioned on opposite side of the second reference hole with respect to the first reference hole.

摘要： Embodiments of the present disclosure provide an optical assembly for high speed optical communications by combining a cover assembly including a lens and a cover post with a body assembly including a lens, reflection prism and body hole, which takes only a few passive optical alignments for providing aligned optical elements that have required multiple complex and sophisticated processes.

摘要： A structure for aligning an optical element includes a baseplate including a set position for mounting at least one optical element, a first reference hole, and a second reference hole spaced by a first distance from the first reference hole. The set position is determined by a first baseline that passes the first reference hole and the second reference hole and a second baseline that intersects with the first baseline at a second distance from the first reference hole on an opposite side to the second reference hole with respect to the first reference hole. The second distance is shorter than the first distance.
