ABSTRACT:
An optical device having at least one slant optical connecting interface is disclosed. The optical device comprises a ferrule assembly, a GRIN rod lens assembly and a means for aligning the interface. The ferrule assembly comprises a pair of optical fibers with the distal ends thereof inserted symmetrically with respect to a reference line in a main body thereof, an aligning reference surface constituted by two surfaces which are provided on the outer periphery of the main body, and an end surface composed of the optical fibers and a main body end surface which have been polished to a slant surface. The GRIN rod lens assembly comprises of a GRIN rod lens, an aligning sleeve supporting the GRIN rod lens, an aligning reference surface which is constituted by two surfaces which are provided on the outer periphery of the aligning sleeve, and an end surface which has been formed by polishing the GRIN rod lens to a slant surface. The means for aligning aligns the reference line of the ferrule assembly with the optical axis of the GRIN rod lens assembly.
