Laser Diode Modelling for Wireless Power Transmission

Free registration required

Executive Summary

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.
