Oscillatory optical response of amorphous plasmonic nanoparticle arrays
Oscillatory optical response amorphous plasmonic nanoparticle arrays Optics
2012/5/29
The optical response of metallic nanoparticle arrays is dominated by localized surface plasmon excitations and is the sum of individual particle contributions modified by inter-particle coupling depen...
Low-loss amorphous Si waveguides with gradient refractive index cladding structure
Low-loss amorphous waveguides gradient refractive index cladding structure
2013/7/3
Amorphous Si waveguides with gradient refractive index cladding structure are proposed and fabricated using plasma-enhanced chemical vapor deposition method. Compared with 6 dB/cm for ridge waveguide ...
Paraxial propagation in disclinated amorphous media
Paraxial propagation disclinated amorphous media
2011/9/8
We study paraxial beam propagation along the wedge axis of a disclinated amorphous medium.The defect-induced inhomogeneity results in Berry phase and curvature that are affected by the induced uniaxia...
