Abstract
  This paper presents a model of the optical waveguide of GaN/ AlN on a sapphire based on the different refractive index (n) between the wave's guideline regions and surrounding medium (cladding). The model analysis is done by using finite-difference mode (FDM) solver simulation is performed by FDTD (finite-difference-time-domain). ...  Read More
