The proposal targets on the first experimental realization of ghost imaging by ultra-broadband amplified spontaneous emission (ASE) based light, emitted by semiconductor-based superluminescent diodes. We exploit the unique property that its first and second order coherence (i.e in field and intensity) can be optimally tailored to achieve finally a true thermal light source, i.e. a source being simultaneously incoherent in first and second order. The ghost imaging application of this source requires novel ultrafast detection techniques on femtosecond correlation timescales adopted to this broad spectrum. The realization and characterisation of these detection techniques and the investigations of the coherence properties of the emitters are in the centre of the application. Comprehensive characterizations of the ghost imaging properties are needed in order to fully explore the understanding and measure the potential of the realized ghost imaging against classical imaging procedures with respect to resolution and limits. We expect that this ultra-broadband ghost imaging on femtosecond correlation times based on mature and sophisticated optoelectronic semiconductor emitters will lead to the realization of real world applications with improved novel imaging performances which demonstration is finally intended within the proposal by three well-selected application examples. Thus the proposal represents quantum optics basic research investigations exploiting an ASE semiconductor source including their wide-spread field of applications.

该提案的目标是通过基于超宽带放大自发辐射（ASE）的光，由基于晶闸管的超发光二极管发射的鬼成像的第一个实验实现。我们利用其第一和第二阶相干性（即场和强度）可以最佳地定制以最终实现真正的热光源，即在第一和第二阶同时不相干的源的独特性质。该源的鬼成像应用需要新的超快检测技术的飞秒相关时间尺度通过这个广泛的频谱。这些检测技术的实现和表征以及发射器的相干特性的调查是应用的中心。需要全面表征的鬼成像属性，以充分探索的理解和衡量的潜力，实现鬼成像对经典的成像程序的分辨率和限制。我们预计，这种基于成熟和复杂的光电半导体发射器的飞秒相关时间的超宽带鬼成像将导致实现真实的世界的应用，具有改进的新颖的成像性能，最终将通过三个精心挑选的应用实例在提案中进行演示。因此，该提案代表了利用ASE半导体源的量子光学基础研究调查，包括其广泛的应用领域。
