Abstract
A method for maximizing the coupling efficiency of a fabricated fiber-optic laser module by deforming the module. In a first embodiment, the method can use a plurality of previously determined influence coefficients to determine how to deform the module, wherein such deformation aligns the focal point of the optical fiber and the laser to maximize the coupling efficiency. Alternatively, in a second embodiment of the present invention, the method is implemented without the use of influence coefficients, wherein the changes in the coupling efficiency resulting from deforming the module are observed to determine which deformations will maximize the coupling efficiency. Irrespective of which embodiment of the present invention is used, the module is deformed to account for its elastic properties by deforming the module beyond the final shape it attains when the coupling efficiency is maximized.
