Microoptics is a branch of optics that has become increasingly important within the last decade. The growing use of optical fiber and integrated optics, especially in communications, creates a need for lenses that can couple light into and out of the various components, such as switches, fiber, and waveguides. Lenses that serve as connectors play a vital role in the overall system performance. Designers of optical systems that couple light into single-mode systems presently have several analytical tools for calculating the coupling efficiency. In the past, the primary tools have been the classical formulas for Gaussian beam propagation. Wagner and Tomlinson advanced the art by proposing a coupling integral which accounts for the aberrations of an optical system. Their method emphasizes analytic forms for the wavefront and development of formulas for the coupling efficiency in terms of the third-order aberrations.
