Abstract :
A 3D FDTD modelling is used to study the effect of surface roughening on the vertical emission of a point source emitting at lambda0=0.94 mum embedded in GaAs with a mirror behind the dipole. Enhancement of emission is seen at lambda0=1.95 mum for a rough-surface device with a perfect metal mirror placed 150 nm below the source
