Multicolor Emission from Ultraviolet GaN-based Photonic Quasicrystal Nanopyramid Structure with Semipolar InxGa1-xN/GaN Multiple Quantum Wells
Keyword(s):
Abstract In this study, we demonstrated large-area high quality multi-color emission from the 12-fold symmetric GaN photonic quasicrystal nanorod device which was fabricated using the nanoimprint lithography technology and multiple quantum wells regrowth procedure. High-efficiency blue and green color emission wavelengths of 460 and 520 nm from the regrown InxGa1−xN/GaN multiple quantum wells were observed under optical pumping conditions. To confirm the strongly coupling between the quantum well emissions and the photonic crystal band-edge resonant modes, the finite-element method (FEM) was applied to perform a simulation of the 12-fold symmetry photonic quasicrystal lattices.
