Enhanced Sensitivity of Absorption-Based Surface Plasmon Interference Sensors in Silicon-On-Insulator by Adsorbed Layer
نویسندگان
چکیده
We present an numerical investigation of a planar waveguide surface plasmon resonance (SPR) sensor in silicon-oninsulator (SOI) for detecting a change in the imaginary part of the refractive index. By adding a thin adsorbed layer between the metal-analyte boundary it is found that an enhanced sensitivity of the sensor is obtained, suggesting the possibility of realizing a highly integrated and highly sensitive absorptionbased SPR sensor in SOI. Keywords-component: SPR biosensors; silicon-on-insulator

Enhanced emission from Si-based light-emitting diodes using surface plasmons
Excitation of surface plasmons on metallic nanoparticles has potential for increasing the absorption and emission from thin Si devices. We report an eight-fold enhancement in electroluminescence from silicon-on-insulator light-emitting diodes at 900 nm via excitation of surface plasmon resonance in silver nanoparticles, along with a redshift in the electroluminescence by 70 nm by overcoating th...

We use the finite element method to numerically analyze the device optical characteristics as a biochemical sensor. As the optical ...
