We present our advances on manipulation of light in metallic nanostructures, including nonlinear control of light transmission in left-handed metamaterials as well as light manipulation on metal surfaces through Airy nondiffracting surface plasmons.
Surface plasmon waveguides consisting of Au stripes in microfluidic channels are highly suitable as biosensors. They are capable of detecting analyte of mass over a very large dynamic range (cells to proteins) with competitive sensitivity.
Surface plasmon amplification by stimulated emission of radiation (spaser) is a nanoscopic quantum generator of coherent local optical fields with high intensity. We will consider the latest development in the theory of spaser and review the large number of experimental data currently available Nanoplasmonics deals with collective electron dynamics on the surface of metal nanostructures, which arises...
The authors propose a universal method to form cylindrically-curved surfaces by dynamically bending in-plane a DRIE-etched flat vertical silicon plate with microactuator. The stiffness is designed position-dependent, thus allowing ideal curvature over large area.
Tapered nanostructures with high aspect ratio were fabricated using high-throughput nanoimprint process. The replicated nanostructures have axially increasing effective refractive index, which enhances the optical transmission over a wide range of wavelengths and incident angles.
Three-dimensional patterning of gold nano-particles on SiO2 and Si substrates is performed by ion-beam lithography with 15–20 nm resolution. Realization of an on-demand achiral and chiral modifications of nano-structures are demonstrated. Simulations of optical properties of the obtained nano-architectures reveal the possibility to tailor the field enhancement both in the spatial and spectral domains,...
Optical nanostructures have the potential to provide useful new functionalities, using materials and fabrication methods that are compatible with standard silicon-based processes. For example, it has been shown that a nanoscale grating coated with a metal layer produces polarization-selective reflectivity [1,2], based on the combined effects of form birefringence and a resonant cavity [3]. In this...
Annealed silver film on top of SiO2 nano-sphere opal shows a dip in the reflection spectrum at photonic band gap wavelengths. Fluorophores coated on the silver film shows over 70 time enhanced fluorescence.
