Abstract:
1. An optical device 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 to an optical path of reflected light which is generated by at least said reflecting function, outside of claddings of said optical fibers, wherein said adhesive layer is on said optical path of reflected light; an anti-reflection film formed on at least one of upper and lower surfaces of said optical element; and a second substrate having a principal surface on which said optical element is mounted; wherein of a gap between said principal surface of said second substrate and said optical element, a gap between at least an active layer of said optical element and said principal surface of said second substrate has no light reflecting member disposed therein.
