Photoluminescence spectra of SiC waveguide in the presence of two-dimensional plasmonic lattice of gold nanoparticles

摘要

In this work, we study theoretically and experimentally the reflection and photoluminescence spectra of SiC slab waveguide with a two-dimensional plasmonic lattice of gold nanodisks. We demonstrate the appearance of the plasmonic modes in the lattice and their interaction with guided modes in SiC slab. Experimental reflection and photoluminescence spectra are in agreement with theoretical predictions.
