Abstract
A diffractive coupling element based on a computer-generated hologram is used in an optical coupling system of a transmitter to control the launch of laser light from a laser light source onto an end of an optical fiber. The diffractive coupling element controls the launch of the laser light such that a desired optical intensity distribution pattern is provided that substantially avoids the center and edge refractive index defects contained in the optical fiber.
