摘要
A recent publication by Statman and Georges reported on the dynamics of electric-field-induced second harmonic (EFISH) in planar germanosilicate waveguides. They provided a model that examines the decay of the second harmonic signal as a result of charge migration inside the doped glass medium through dielectric relaxation and electronic drift. We present experimental results of EFISH using femtosecond laser pulses. We show here that this decay is actually due to the formation of a surface charge.
