Abstract

In this paper we investigate the use of two similar photosensitive dyes that are used in the creation of photosensitive polymers. The specific dyes are what makes the photopolymer material responsive to specific wavelength that the polymer material is exposed to. The subsequent self-written waveguides (SWW) that are created are a product of this interaction between the light beam, photopolymer material and the sensitive dye. We investigate the optical characteristics and light propagation comparisons between the two dyes and the their photosensitive response associated with specific wavelengths.
