Abstract

This invention discloses an optical device including at least one first substrate defining a multiplicity of optical fiber positioning grooves (22), a multiplicity of optical fibers (20) fixed in each of said multiplicity of optical fiber (20) positioning grooves on the at least one first substrate (24), whereby the multiplicity of optical fibers (20) lie in an optical fiber plane and the ends of each of the multiplicity of optical fibers (20) lie substantially in a first predetermined arrangement in the optical fiber plane, a second substrate fixed onto the at least one first substrate such that an edge of the second substrate extends beyond the ends of each of the multiplicity of optical fibers (20), a lens assembly including a third substrate, and a lens fixed onto the third substrate, the lens assembly (40) being mounted onto the second substrate (42) such that the lens lies in a second predetermined arrangement with respect to the ends of each of the multiplicity of optical fibers, whereby the separation between the lens and the ends of each of the multiplicity of optical fibers is defined in a plane perpendicular to the optical fibers plane to a first degree of accuracy, less than the first degree of accuracy.
