چکیده
We design and numerically model a 3D nanoring-nanodisk structure evaluate the effect of ring disk radii size within presented on optical enhancement. Nanoring-nanodisk is powerful for enhancing local electric field photo-sensing applications. present an enhanced from UV to IR wavelength range using proposed with fixed nanogap. It shows strong dependence radius structure. In addition, two distinct peaks have different plasmonic vibrational modes appearing in spectrum. These are revealed by surface charge distributions. Moreover, our calculations reveal that smaller larger can generate more

Gold Nanoring Arrays for Near Infrared Plasmonic Biosensing
Gold nanoring array surfaces that exhibit strong localized surface plasmon resonances (LSPR) at near infrared (NIR) wavelengths from 1.1 to 1.6 μm were used as highly sensitive real-time refractive index biosensors. Arrays of gold nanorings with tunable diameter, width, and spacing were created by the nanoscale electrodeposition of gold nanorings onto lithographically patterned nanohole array c...
متن کاملGold nanoring trimers: a versatile structure for infrared sensing.
In this work we report on the observation of surface plasmon properties of periodic arrays of gold nanoring trimers fabricated by electron beam lithography. It is shown that the localized surface plasmon resonances of such gold ring trimers occur in the infrared spectral region and are strongly influenced by the nanoring geometry and their relative positions. Based on numerical simulations of t...

متن کاملOptical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods
An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...
متن کاملUtilization of Field Enhancement in Plasmonic Waveguides for Subwavelength Light-Guiding, Polarization Handling, Heating, and Optical Sensing
Plasmonic nanostructures have attracted intensive attention for many applications in recent years because of the field enhancement at the metal/dielectric interface. First, this strong field enhancement makes it possible to break the diffraction limit and enable subwavelength optical waveguiding, which is desired for nanophotonic integrated circuits with ultra-high integration density. Second, ...
