Abstract
An optical component is constructed in such structure that a plurality of optical fibers are arranged in parallel to each other and the component has an entrance surface obliquely cut relative to the optical axis and an exit surface normally cut relative to the optical axis. The cross section of the optical component is shaped so that optical fiber pairs, each pair being such a combination of two optical fibers with cores of semicircular cross section as to form a substantially circular cross section, are arranged regularly. Orientation of two semicircular cores forming the optical fiber pair is random in each optical fiber pair. Cladding of each optical fiber is provided so as to be integrated by a heating and pressing process to fill a clearance between cores of two optical fibers forming the optical fiber pair of interest and clearances between adjacent optical fiber pairs.
