ICO-PHOTONICS-DELPHI2009, was a scientific forum dedicated to Emerging Trends and Novel Materials in Photonics, organized by the Hellenic Optical Society under the auspices of the International Commission for Optics. The overwhelming success fulfilled its goals, bringing together optics and materials communities and establishing a common scientific vision at the interfaces of photonics and nanotechnologies. In this context, the volume presents advanced concepts and trends of novel photonic materials and functional photonic structures, from the advanced fabrication issues such laser induced organization and processing of functional devices, to quantum and ultrafast effects in nanostructures, to photonic devices for information and biophotonics technologies. It is directed to the professional in research and industry and will be of benefit to the graduate student working in the fields of photonics and nanotechnologies.
