Abstract
Holographic gratings that have been created through the exposing of a specific light beam upon a photosensitive polymer material have been known to also produce self-written waveguides (SWW). We will investigate the SWW and its ability to propagate an optical beam along its path. The reproduction of images processed as information within an optical beam and propagated along the SWW will be tested. The image will be analysed for coherence and clarity. The effect of Birefringence upon the information or image and its optical characteristics will be interrogated measured. The probably of information distortion and the presence will be studied and analysed through research, experimentation and numerical modelling.
