The photonic systems laboratory (PHOSL) research topics are centered around the study of optical nonlinear processes in waveguides, such as silica step index fibers, soft-glasses microstructured fibers or integrated (CMOS fabrication process compatible) waveguides. In the last decades, the versatile and complex nature of nonlinear effects has established them as unique optical processing devices and light sources. Nonlinear effects in waveguides are indeed an elegant and powerful technique to achieve all-optical ultra-fast processing, efficient frequency mixing and wavelength conversion. Our research is thus aimed at the design of efficient and flexible devices for use in all-optical systems and the study of novel waveguiding structures for enhanced nonlinear properties outside of the telecommunication bands, such as the middle infrared.
