3D FDTD modelling is employed to design a surface pattern for mid-IR LEDs. Measured enhancement factors over an un-patterned device of 8% and 14% are found at 300 K and 25 K respectively. 3D FDTD modelling is employed to design a surface pattern for

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

Three-dimensional numerical modeling of emission from InSb light-emitting diodes with patterned surfaces

Autor: John Rarity, Geoffrey R. Nash, IJ Buss, Martin J Cryan

Publikováno v: Journal of the Optical Society of America B. 25:810

Full 3D numerical modeling is undertaken on light-emitting diode structures with patterned surfaces represented by regular, pseudorandomly disordered, and uniformly distributed random arrays of square holes to investigate both grating and random scat
