Abstract
An optical device having a multiplicity of optical fibers fixed in respective grooves in a first substrate in a predetermined arrangement in an optical fiber plane. A second substrate is fixed onto the first substrate such that an edge of the second substrate extends beyond the ends of the optical fibers. A lens assembly including a third substrate, and a lens fixed on the third substrate is mounted on the second substrate such that the lens lies in a second predetermined arrangement with respect to the ends of the optical fibers and is spaced from them in a plane perpendicular to the optical fiber plane with a first degree of accuracy and in the optical fiber plane with a lesser second degree of accuracy.
