Abstract:In this paper the design and modelling of an integrated Al2O3:Er3+ distributed feedback laser (DFB) is presented. The implemented laser model combines rate equations of the population mechanisms in the erbium ion with coupled-mode theory. The model enables the estimation of the optimum Bragg grating design that is required in order to realise such a DFB laser device. Based on the modelling results, the ideal grating geometry has been identified and fabricated by making use of laser interference lithography (LIL) and reactive ion etching (RIE). Optical characterisation experiments of the gratings are currently in progress.
