Within this project “Tabasco”, a photonic RF upconversion scheme shall be researched and implemented. The preliminary work indicates that the self-imaging Talbot effect offers the possibility of phase noise suppression during the RF generation process. Overcoming fundamental limitations of electronic upconversion, this approach paves the way for low-noise RF carriers in the millimeter wave range. Talbot effect based upconversion has already been experimentally shown. However, the required dispersive element has been realized with fibers or fiber bragg gratings which has some drawbacks: The resulting setup is bulky and prone to environmental effects.The planned realization of the upconversion stage within Tabasco tackles these issues. Co-integrating the photodiode for opto-electrical conversion with the optical dispersive element enables higher bandwidths. Moreover, the envisioned on-chip solution will be small, robust and potentially cost-effective because it will be realized in standard SiGe EPIC technology. This technology has the potential to add further electronic functionality such as amplification, mixers or even complete front-ends.

在“塔巴斯科”项目中，将研究和实现光子RF上变频方案。初步工作表明，自成像塔尔博特效应提供了在射频产生过程中抑制相位噪声的可能性。这种方法克服了电子上变频的基本限制，为毫米波范围内的低噪声RF载波铺平了道路。基于塔尔博特效应的上转换已经在实验上显示。然而，所需的色散元件已经用光纤或光纤布拉格光栅实现，这有一些缺点：由此产生的装置体积庞大，容易受到环境影响。计划在Tabasco内实现的上转换级解决了这些问题。将用于光电转换的光电二极管与光色散元件共同集成能够实现更高的带宽。此外，设想的片上解决方案将体积小、功能强大且具有潜在的成本效益，因为它将在标准SiGe EPIC技术中实现。这项技术有可能增加更多的电子功能，如放大，混频器甚至完整的前端。
