Enhancement of blue light emission using surface plasmons coupling with quantum wells
TLDR
In this paper, the FDTD method is used to simulate the enhanced blue light emission of gallium nitride light emitting diode (GaN-LED) using the surfaceplasmons (SPs) cou- pling with the quantum wells.Abstract:
dimension flnite-difierence time-domain (FDTD) method is used to simulate the enhanced blue light emission of gallium nitride light emitting diode (GaN-LED) using the surface-plasmons (SPs) cou- pling with the quantum wells. The numerical simulation results demon- strate that when the silver fllm is coated on GaN-LED, the excited SPs play a key role in the enhanced blue light emission, and the en- hancement depends on the geometries of GaN-LED and silver fllm. An enhancement factor is given to describe the enhancement efiect of light emission. By changing the structure parameters of GaN-LED and sil- ver fllm, the enhanced peak of the light emission in the visible region can be controlled. Under the optimal parameters, about 17 times en- hancement at 460nm can be obtained, and the enhancement efiect is evidently demonstrated by the SPs fleld distribution.read more

Numerical solution of initial boundary value problems involving maxwell's equations in isotropic media
Abstract: Maxwell's equations are replaced by a set of finite difference equations. It is shown that if one chooses the field points appropriately, the set of finite difference equations is applicable for a boundary condition involving perfectly conducting surfaces. An example is given of the scattering of an electromagnetic pulse by a perfectly conducting cylinder.
