Theory of second-harmonic generation in colloidal crystals
J. P. Huang, Y. C. Jian, C. Z. Fan +1
On the basis of the Edward-Kornfeld formulation, we study the effective susceptibility of secondharmonic generation (SHG) in colloidal crystals, which are made of graded metallodie…
Dispersion and transitions of dipolar plasmon modes in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
Coupled plasmon modes are studied in graded plasmonic waveguides, which are periodic chains of metallic nanoparticles embedded in a host with gradually varying refractive indices.…
Optical switching in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
A new mechanism of longitudinal confinement of optical energy via coupled plasmon modes is proposed in chains of noble metal nanoparticles embedded in a graded dielectric medium, w…
Giant enhanced optical nonlinearity of colloidal nanocrystals with a graded-index host
J. J. Xiao, K. W. Yu
The effective linear and third-order nonlinear optical properties of metallic colloidal crystal immersed in a graded-index host fluid are investigated theoretically. The local elec…
