Evolutionary optimization of non-periodic coupled-cavity semiconductor laser diodes

The analysis of different types of non-periodic multi-cavity laser structures will be presented. Deterministic non-periodic cavity concepts such as self-similar Cantor- or quasi-periodic Fibonacci sequences offer a distinct mode selectivity whilst having a significantly lower number of coupled cavities compared to an equivalent periodic solution. A heuristic numerical optimization procedure based on a breeder genetic algorithm scheme is favoured, also to give a sort of general information as to which kind of structures are well suited in terms of our requirements. By investigating the evolutionary optimized laser topologies according to the evolution of characteristic patterns, we propose a sort of superior meta-optimization strategy which relies on a population based information gathering.
