Abstract: Techniques for coupling light from a waveguide array to a single mode fiber array are described. In an embodiment, lateral misalignment of an array of focusing lenses and an array of optical fiber ferrules held into alignment by a lens holder sub-assembly is compensated by tilting the lens holder sub-assembly with respect to the propagation axis of the light being coupled by the lens holder-subassembly. Since the amount of tilt can be adjusted according to the degree of lateral misalignment, lens holder sub-assemblies manufactured with varying degrees of misalignment may be utilized to couple light into single mode fiber-optic cable. In addition, the same technique can also be used to compensate for other defects as well, such as angular errors in manufacturing or placement of a turning mirror or prism used to direct light into the lens holder sub-assembly.
