Parametric fluorescence generation in LiNbO3 quasi-phase matched waveguide pumped by semiconductor laser

We designed and fabricated a device for parametric fluorescence generation in the 1.5 mum band. The parametric fluorescence generation by pumping with a semiconductor laser was obtained. The fluorescence wavelengths and the spectrum were in good agreement with the theoretical prediction. Measured fluorescence power 2.2 nW for 12 mW pumping was in the same order of magnitude with the theoretical prediction.
