MULTILAYERGRAPHENEfiberBRAGGGRATINGGRAPHENECLADDINGrefractiveindexGraphene's optical absorption coefficient increases linearly with the number of layers making it more effective in the construction of optical tuning graphene-based devices.Refractive index (RI)is one of the important optical parameters of the ...
In addition, both methods showed that the presented structure could sort the particles entering the liquid according to their refractive index. The primary physical mechanism of both methods in the proposed structure is to control the force on the particle moving inside the channel, which can be ...

It also could utilized for probing the refractive index of dielectrics or the loss coefficient of materials based on Goos-Hänchen shift [28], [29]. The structure can be stacked with slices of MgF2 and ZnS. Each slice generates through chemical vapor deposition (CVD) method. The chemical ...
In particular, a negative refractive index is straightforward to realize in graphene, but hard in optics. If time permits, we will discuss recent results on microwave absorbtion in suspended bilayer graphene sheding light on thermoelectrics, as...
As a result, refractive index was changed and thus the resonance wavelength of surface plasmon was shifted. In order to confirm the experimental results, Kerr nonlinear effect of graphene, and optical electric field distribution at resonance wavelength have been simulated. Based on the results, this...
In addition, the resonance wavelength highly depends on the geometrical parameters, such as the period of the diffraction grating, the duty cycle, the optical thickness of the waveguide layer, and the refractive index of a surrounding material3,4. Due to these characteristics, GMR filters have ...
