At present optical technology is one of the most rapidly developing areas of science and technology. Continuously increasing demands of the society for high-speed and reliable systems of information transmission have led to the development of waveguide optics and of methods for creation of waveguides in different media. Easiest way of creating waveguides and complex waveguide networks in different media is direct femtosecond writing. Writing waveguides in polymers is a just developing field, polymer materials are very cheap and have the potential to create complex structures inside the volume of the material. In polymers the refractive index increase is induced by material compression and stress-related effects which are caused by a quickly expanding plasma core. Once the modification is done, there is an area where material is compressed and the index increased. This area can be used as optical waveguide. In this work we want to demonstrate different waveguide structures which can be produced inside polymer materials.
