Metallodielectric Multilayer Stacks Show Enhanced Ultrafast Optical Nonlinear Response

摘要

In the December 1, 2007 issue of Optics Letters (p. 3435), G. Ma and S.H. Tang of Shanghai University in China and the National University of Singapore, respectively, reported the enhancement of the nonlinear optical response in Ag-TiO_2 multilayer stacks determined through femtosecond optical Kerr effect measurements.
