Abstract
In an optical fiber-lens array, the optical axes of the gradient index rod lens and of the optical fiber are aligned easily with high accuracy. The optical fiber-lens array includes a first substrate having a gradient index rod lens accommodated in V-shaped grooves for rod lenses formed in parallel at prescribed pitches, and a second substrate having optical fibers accommodated in V-shaped grooves for optical fibers formed at the same array pitches with said V-shaped grooves for rod lenses. The first substrate and the second substrate are connected by guide pins placed on the common positioning guide grooves formed on the first substrate and the second substrate with the respective end surfaces of the gradient index rod lenses and the respective end surfaces of the corresponding optical fibers faced toward each other.
