Laser Diode Modelling for Wireless Power Transmission
Wireless power transmission using laser beaming can be realized with arrays of high power semiconductor laser diodes. In this paper, the authors present a complete model for a single power emitter diode characterized by a tapered amplifying section and a quantum well active layer. The band mixing technique has been used for gain calculation and the Transmission Line Laser Modelling (TLLM) for evaluating the electromagnetic propagation inside a tapered waveguide. Moreover, they present a complete time domain analysis, which allows to include non linear effects. The model has been completed with a proper set of rate equation for carrier distribution and sources to take into account the Amplified Spontaneous Emission (ASE) noise.
