Abstract :
In this paper, we first review the theoretical model and numerical algorithm for the simulation study of the surface plasmon (SP) coupling with a radiating dipole in an InGaN/GaN quantum well to demonstrate the advantages of SP-coupled light-emitting diode (LED) in the visible range, including internal quantum efficiency enhancement, droop effect reduction, and modulation bandwidth increase. Then, we apply the similar method for investigating the SP coupling behavior in a deep UV LED for showing its functions of reducing p-GaN absorption and suppressing TM-polarized emission.
