Hybrid organic/inorganic waveguide structure with highly efficient second order nonlinear interactions

Summary form only given. We consider hybrid planar waveguides which are constituted of ion-exchanged glass substrates top covered by high index polymer layers. They have been specially designed and fabricated for a highly efficient nonlinear interaction. Without any corrugation, phase-matching between the different waves is realized thanks to the use of different guided modes at the different wavelengths. This is called modal dispersion phase matching (MDPM). In this communication we report on second harmonic generation after a longer propagation in the waveguide of 5mm.
