Abstract

The mode coupling of hollow infrared optical fibers was investigated as a function of beam launching conditions, i.e. fiber transverse and longitudinal misalignment and tilting. Experimental results with a TEM00 carbon-dioxide laser and hollow sapphire and dielectric coated metallic waveguides are compared with geometrical optics and mode coupling theories. ©2005 Copyright SPIE - The International Society for Optical Engineering.
