The creation of self-trapping waveguides within a photopolymer material and the resultant permanent self-writtenwaveguides (SWW) has been investigated for their propagation properties. We look at two light beams as they convergeon the photopolymer and interact with the material to produce two separate waveguides fabricated within the material.Here we study these self-written waveguides and investigate their coupling as they propagate within the PVA/AA andcombine to form a single SWW within the material. The angle of insertion is interrogated to identify the best angle toproduce the SWW coupling effect. The single coupled SWW that is produced, is measured for attenuation so as tocharacterize the coupled waveguide.
