Femtosecond third-order nonlinear spectra of lead-germanium oxide glasses containing silver nanoparticles

Year: 2012

Type: article

Abstract: This work reports on the spectral dependence of both nonlinear refraction and absorption in lead-germanium oxide glasses (PbO-GeO₂) containing silver nanoparticles. We have found that this material is suitable for all-optical switching at telecom wavelengths but at the visible range it behaves either as a saturable absorber or as an optical limiter.
