Department of Applied Physics, Osaka University, Yamadaoka 2-1,Suita, Osaka 565-0871, JapanNanophotonics Laboratory, RIKEN, Wako, 351-0198, Japanhttp://lasie.ap.eng.osaka-u.ac.jp/Received 3 August 2002We present an overview of the physics of self-written waveguides created in photosen-sitive optical materials, including the experimental observations and the correspondingtheoretical models for describing the growth of both bright and dark self-written beams.We discuss in more details the properties of self-written waveguides created in photosen-sitive polymers, which have been discovered in the recent experimental and theoreticalstudies. The self-writing process is essentially a nonlinear phenomenon, since the tempo-ral dynamics depends on the optical exposure. Under appropriate conditions, permanentlarge changes in the refractive index are induced along the propagation direction of anoptical beam, so that optical channels, or \ laments", appear as waveguides becoming\frozen" in a photosensitive material. We describe the growth of individual lamentsas well as the interaction of several laments, also making a comparison between thephysics of self-written waveguides and the concept of spatial optical solitons in self-focusing nonlinear media.Keywords: Self-written waveguide; spatial soliton; nonlinear response; photosensitivematerial; photopolymers; self-action of light.
