Abstract
The end face of an optical fiber 11 is polished at an angle to alter the cross-sectional dimensions of a light beam exiting the fiber through that end face to alter the cross-sectional circularity of the light beam after it has exited the fiber as compared to its cross-sectional circularity when it is in the fiber. For example, to increase the circularity of an exiting light beam, the angled fiber end face can be aligned such that the major axis of the sloping fiber end face is aligned with the major cross-sectional axis of the light beam in the fiber (i.e. perpendicular to the minor cross-sectional axis of the light beam in the fiber). This has the effect of reducing the length of the major cross-sectional axis of the light beam once it has exited the fiber.
