  Définition

  In a cylindrically symmetric waveguide, the optical axis is the axis of geometric symmetry of the core.

  Notes :

  Distinguished from "optic axis".
  
  In rare cases, an optical system will contain one or more elements (usually mirrors) whose axes are tilted with respect to one another. In such cases the optical axis is ill defined but could be taken to follow the line segments that join the centers of the aperture stops of the tilted components.
  
  The optical axis of a waveguide is the axis of the waveguide and therefore need not be straight line.
