Abstract: A method for aligning an optical assembly, including the steps of emitting at least one beam from an emitter substantially along a first axis, disposing a cylindrical lens in said at least one beam to form at least one line image, wherein a longitudinal axis of said cylinder lens is substantially parallel to a second axis which is different from said first axis, displaying at least one vertical profile of said at least one line image, defocusing said at least one line image until a first peak and a second peak of said at least one profile are displayed and adjusting in a third axis which is different from said first axis and said second axis a position of said cylindrical lens relative to said emitter until said first peak and said second peak are symmetric.

Abstract: A method for accurately mounting an optical element in an optical assembly including precisely positioning the optical element in a desired position with respect to a reference surface and spaced from the reference surface and employing an adhesive for fixing the optical element in the desired position including employing at least one side mounting element separate from the reference surface including at least one first surface which engages an edge of the optical element and at least one second surface which engages the reference surface.

Abstract: An optical device in which a waveguide is mounted on an optical substrate in turn supported on a base substrate. The base substrate is provided with an optical fiber positioning groove into which an optical fiber is fixed so that a center of the fiber lies in a plane substantially coplanar with a plane of the waveguide.

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.
