Patent ID: 7287915

Claim:
An optical device comprising: an optical head; and a package housing said optical head therein and having pins extending outwardly; said optical head comprising: a first substrate with V-shaped grooves defined therein; one or more optical fibers fixed in the V-shaped grooves in said first substrate, said optical fibers having a reflecting function; an optical element fixed by an adhesive layer directly to said one or more optical fibers so as to lie on an optical path of reflected light, which is generated by at least said reflecting function, outside of claddings of said optical fibers; and a second substrate on which said optical element is mounted, wherein said second substrate has a mounting surface on which said optical element is mounted, said mounting surface being disposed in confronting relation to said first substrate; wherein said optical element and said pins of said package are electrically connected to each other by a conductive pattern disposed on said second substrate, and wherein said reflected light passes from said one or more optical fibers into said optical element without passing through said first substrate.
