Optimization of Semiconductor Bragg Mirrors with Genetic Algorithms

We present application of a genetic algorithm for optimization of dispersive properties of Bragg reflectors used in femtosecond lasers. The aim of the optimization is designing a mirror with broadband, large negative group delay dispersion (GDD). We were able to achieve GDD of -3500 fs² over a 10 nm...

Summary:We present application of a genetic algorithm for optimization of dispersive properties of Bragg reflectors used in femtosecond lasers. The aim of the optimization is designing a mirror with broadband, large negative group delay dispersion (GDD). We were able to achieve GDD of -3500 fs² over a 10 nm bandwidth. We have manufactured the optimized structures with molecular beam epitaxy and verified its performance in a passively mode-locked Yb:KYW laser.
