The creation of self-trapping waveguides within a photopolymer material and the resultant permanent self-written waveguides (SWW) has been investigated for their propagation properties. We look at two light beams as they converge on 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 and combine to form a single SWW within the material. The angle of insertion is interrogated to identify the best angle to produce the SWW coupling effect. The single coupled SWW that is produced, is measured for attenuation so as to characterize the coupled waveguide.
