D. Ochoa et al., Spontaneous emission model of lateral light extraction from heterostructure light-emitting diodes, APPL PHYS L, 76(22), 2000, pp. 3179-3181
We investigate the extraction of light from semiconductor light-emitting di
odes made of dielectric multilayer stacks with quantum-well sources. The mo
del is a combination of a rigorous vertical model of dipole emission and an
in-plane ray-tracing model. The vertical model is shown to conveniently pr
ovide the relevant horizontal decay length of the various kinds of in-plane
propagating modes. The proposed combination of the two models accounts for
the lateral extraction as well as light recycling in the active layers. (C
