Abstract:Photonic crystals (PhC) are of special interest in the applications of linear and non-linear optics, as the dispersion of light inside these periodic structures is strongly modified. In this thesis, we present a method to probe the guided modes of a 2D PhC slab that was fabricated for possible non-linear applications. As the guided modes are confined to the PhC slab, a coupling setup had to be devised to access these modes. A coupling setup based on attenuated total reflectance (ATR) was designed and built, and the mid-infrared (MIR) radiation from an optical parametric oscillator (OPO) was used. The measurements performed using this setup are presented and compared to theoretical expectations.
