Third-order nonlinear optical properties and optical switching of palladium (I) complex

Abstract

We report the third-order nonlinear optical, optical power limiting and optical switching study of palladium-N-(2-pyridyl)-N?- (5-amino salicylidene) hydrazine triphenylphosphine, using Z-scan technique and pump-probe technique. The measured nonlinear refractive index is n 2=-6.022�10-9esu. The complex exhibits the reverse saturable absorption (RSA), the nonlinear absorption coefficient of ?=10.748�10-9m/W. The good optical power limiting and optical switching behavior were observed in this complex. These suggest that this complex is a potential molecule for photonic applications. � 2011 American Institute of Physics.
