The linear propagation properties of laser written hexagonal waveguide arrays in fused silica have been studied for the first time. We determine the behavior of the coupling constants for different waveguide separations and for different wavelengths.

We present results on the generation of tunable continuous-wave THz radiation via photomixing on a PCA using a dual mode external cavity diode laser (2λ-ECDL). The tuning range reaches from 250GHz up to several THz.

We present calculations concerning the generation of terahertz waves by difference frequency generation (DFG) using mid-infrared (MIR) radiation. We investigate phase matching conditions using a waveguide design for semiconductor materials like GaAs,

We report on the investigation of the nonlinear refractive index in femtosecond laser written waveguide arrays in fused silica. The nonlinear refractive index is significantly reduced compared to the unmodified material. Due to the dependence of the

In this presentation, we report on investigations of the nonlinearity of fs-laser written waveguides in fused silica. To determine the nonlinear refractive index change, we investigated the evolution of the spectrum due to self-phase modulation durin

We report on the measurement of the nonlinear refractive index of fs-laser written waveguides in fused silica by analyzing self-phase modulation of the propagating light. The nonlinear index is reduced considerably compared to the bulk material by th
