Résumé en anglais

Second-harmonic and terahertz generation are performed in Rb0.94Mn[Fe(CN)6]0.98.0.3H2O Prussian-blue-analog. Second-harmonic generation experiments are carried out in between 1100 and 1700 nm and within the hysteresis loop of this compound. In the low and high temperature phases, our measurements indicate that the effective second-order nonlinear component χ (2) of this material is small compared to -Quartz. However at high temperature phase and close to 1100 nm, its χ (2) is enhanced by more than one order of magnitude. Terahertz generation performed indicates that in this frequency range, the effective χ (2) of this compound is high and comparable to ZnTe. Finally we demonstrate that, within the thermal hysteresis loop of this Prussian-blue-analog, one can modulate the χ (2) by photo-switching it from the low temperature to the high temperature phase.< Réduire
