项目摘要
Microcavities are an ideal model system to investigate the transition from ordered to disordered photonic structures, furthermore, they immediately lead to interesting application perspectives. The aim of this project is thus the investigation of metal-organic microcavities (MCs) with additional lateral patterning leading to a spatial, angular, and spectral control of the spontaneous and stimulated emission modes in organic microlasers. Starting from single photonic wires and periodic wire arrays inside of such MCs, we plan to introduce finely tunable defects enhancing trapping of light, increasing the density of optical states, and finally leading to improved device characteristics such as a decrease of lasing thresholds in organic lasers. Furthermore, aperiodic and quasi-crystal-like patterning is to be investigated, with a systematic study of the transition from periodic to aperiodic to completely disordered patterns, utilizing high-resolution near and far field spectroscopy as well as mapping the temporal field development in such cavities. Finally, the suitability of such metallic patterns for charge carrier injection in MC-light emitting diodes and -lasers is to be investigated. The results of this project should provide a basis for novel or significantly improved photonic devices.
微腔是研究光子结构从有序到无序转变的理想模型系统,并且具有很好的应用前景。因此,该项目的目的是调查金属有机微腔(MC)与额外的横向图案,导致在有机微激光器的自发和受激发射模式的空间,角度和光谱控制。从单光子线和周期性线阵列内的这种MC开始,我们计划引入精细可调的缺陷,增强光的捕获,增加光学状态的密度,并最终导致改善的器件特性,如在有机激光器中的激光阈值的降低。此外,非周期性和准晶体状图案的研究,从周期性的过渡到非周期性的完全无序的模式,利用高分辨率的近场和远场光谱,以及映射的时间字段的发展,这样的腔体的系统研究。最后,这种金属图案的电荷载流子注入MC-发光二极管和激光器的适用性进行了研究。该项目的结果将为新型或显著改进的光子器件提供基础。
