Abstract
An optical device for implementing passive alignment of parts and a method therefor, more particularly an optical device and a method therefor that utilize an alignment reference part arranged on the substrate to passively align an optical element part with a lens-optical fiber connection part. For the passive alignment of parts, connection pillars of an alignment reference part are coupled to substrate holes, one or more light-emitting elements and one or more light-receiving elements are aligned in a row in a particular interval with respect to alignment holes arranged opposite each other in the alignment reference part, a lens-optical fiber connection part is aligned with respect to the alignment holes, and an optical fiber is aligned with the optical alignment point at a surface of a prism forming a portion of the lens-optical fiber connection part.
