In the work reported here we use the finite-difference time-domain method to model an ordered nanorod array incorporated in a vertical LED structure in place of the surface roughened region. The simulations reveal that diffraction dominates the far field emission when the emissive layer lies below the nanorod array, as might occur in a vertical LED structure with the NR layer used as a light extracting...
The results of 3D FDTD calculations of out-of-plane radiation losses in slow light regime for a 2D Silicon-On-Insulator (SOI) Photonic Crystal (PhC) slab are presented. In a 2D PhC slab structure periodicity causes a scattering out of waveguiding modes to the radiating modes. Optical sensors based on 2D PhCs working in slow light regime call for long devices in order to make the path of light propagation...
