Commercial optical transmission systems achieve data rates of 100 Gb/s on a single wave length. Future systems in communications are targeting for more than 1 Tb/s to meet the worldwide needs of increasing data rates in communications. In literature and in the appli-cants’ own preliminary work, the combination of silicon photonics with organic electro-optical materials offers promising results, e.g. with electro-optical bandwidths better than 100 GHz. In this proposal, the properties of nanostructured modulators and electro-optical active organic films should be investigated and correlated using the mentioned organic silicon-hybrid-modulator concept. The strongly interdisciplinary project combines the expertise of synthesis and film processing (Ludwigs, IPOC) with the expertise of modulator design and measure-ment technology (Berroth, INT). The investigation and fabrication of tailored electro-optical active films with enhanced stability for the application in the field of integrated photonics are main issues. A temperature-stable modulator should be investigated and realized with a fiber-to-fiber loss smaller than 4 dB, achieving bandwidths larger than 100 GHz and extinction ratios of more than 20 dB. The implementation of dual-mode interferometers, plasmonic waveguides and the process optimization of the chromophore alignment with the help of a special annealing-method using solvent vapor will be evaluated. Besides the synthesis of novel chromphores including acceptor-groups with high electron-withdrawing properties, the improvement of the temperature properties with the help of in-situ cross-linking reactions is scheduled. Due to the cooperation of the involved institutes, the investigation, fabrication and optimization can be done in Stuttgart.

商用光传输系统在单个波长上实现100 Gb/s的数据速率。未来的通信系统的目标是超过1 Tb/s，以满足通信中不断增加的数据速率的全球需求。在文献和申请人自己的初步工作中，硅光子学与有机电光材料的组合提供了有希望的结果，例如，电光带宽优于100 GHz。在这个提议中，纳米结构调制器和电光活性有机膜的性质应该使用所提到的有机硅混合调制器概念进行研究和关联。这个跨学科的项目将合成和胶片处理（Ludwigs，IPOC）的专业知识与调制器设计和测量技术（Berroth，INT）的专业知识相结合。研究和制备具有高稳定性的可定制电光活性薄膜是集成光子学领域的主要问题。一个温度稳定的调制器应进行研究和实现的光纤到光纤的损耗小于4 dB，实现大于100 GHz的带宽和消光比大于20 dB。将评估双模干涉仪，等离子体激元波导的实现以及在使用溶剂蒸气的特殊退火方法的帮助下的发色团对准的过程优化。除了合成包含具有高吸电子性能的受体基团的新型发色团外，还计划通过原位交联反应来改善温度性能。由于相关机构的合作，研究，制造和优化可以在斯图加特进行。
