Light Emission and Localization in Photonic Clusters and Random Lasers

光子团簇和随机激光中的光发射和局域化。最近的实验进展展示了在光波长尺度上构建的人工和自然系统令人惊讶的光学特性。我们将对这样的系统进行数字建模，提供对放置在其中的原子的辐射如何改变的见解，光散射可以导致没有反射镜的激光，它们的精细结构可以产生永不褪色的颜色，光可以在三维中局部化或捕获。

Light Emission and Localization in Photonic Clusters and Random Lasers. Recent experimental advances have exhibited surprising optical properties of artificial and natural systems structured on the scale of the wavelength of light. We will model numerically such systems, providing insights into the way radiation from atoms placed in them can be changed, light scattering can lead to lasers without mirrors, their fine structure can result in colours which never fade, and light can be localized or trapped in three dimensions.
