Abstract
A new lumped equivalent circuit for light emitting diodes (LED's) is presented which models the electrical and optical performance incorporating linear and nonlinear recombination mechanisms. Most of the model parameters can be determined from electrical measurements. The model is tested by experiments with different types of LED's and its use in connection with SCEPTRE is demonstrated by a simulation of a 200 Mbits/s pulse code modulation (PCM) pulse train. Special attention is devoted to the electrical reverse recovery behavior of LED's.Keywords
