Self-Writing of optical waveguides has been demonstrated in the photopolymerizable materials. The unique self-writing phenomenon is due to the balance of light wave diffraction and confinement through the increase in index of refraction during polymerization. In cases the competition of the initial diffraction and photo-polymerization, leading to increase the refractive index, the beam can be self-trapped along the propagation axis.
