无序反蛋白石中的动态光扩散、安德森局域化和激光:3D从头算Maxwell-Bloch计算

Dynamic light diffusion, Anderson localization and lasing in disordered inverted opals: 3D ab-initio Maxwell-Bloch computation

Claudio Conti, Andrea Fratalocchi

摘要:

我们报道了在具有完全光子带隙的倒置无序蛋白石中光的安德森局域化的三维时域并行模拟。研究了飞秒激光激发下的动态扩散过程,计算了扩散常数和衰变时间随无序强度的变化。我们报告的证据,从离域布洛赫振荡过渡到强烈的本地化共振自启动激光过程。

英文摘要:

We report on 3D time-domain parallel simulations of Anderson localization of light in inverted disordered opals displaying a complete photonic band-gap. We investigate dynamic diffusion processes induced by femtosecond laser excitations, calculate the diffusion constant and the decay-time distribution versus the strength of the disorder. We report evidence of the transition from delocalized Bloch oscillations to strongly localized resonances in self-starting laser processes.
