Abstract :
In this work, we present a new physically based model of an integrated photodetector as part of a BD-system (blu-ray-disc, λ=405 nm). This model takes care on the transport phenomena within the photodiode as well as of the RC time constant of the device. The model properly predicts the photocurrent of the diode and can be used e.g. as AHDL model in commercial circuit simulators for dc, ac and transient simulations. To demonstrate the accuracy of the model we have compared our results with simulation data using the numerical device simulator Atlas/Silvaco.
