CIRCULIGHT - Circulating Light on any Photonic Platform

CIRCULIGHT中设想的新技术将在光子集成电路（PIC）能力方面取得突破，并对具有高经济和社会价值的广泛应用产生影响。它将为新型PIC奠定基础，这些PIC具有高功能、小型化和低功耗，并且可以低成本制造，从而大大有助于环境保护和相关的生活质量。该项目中将创建的基本构建块是一个真正集成的光环行器，它保护有源和无源集成功能，在它们之间分配光，并最终允许在多样化的PIC架构中大规模集成光子组件。这种结构的实际实现将是世界首创，也是PIC技术的突破。CIRCULIGHT技术的决定性进展是基于磁光（MO）纳米颗粒复合溶胶-凝胶材料和磁双等离子体（MBP）效应，这将使循环器在任何光子平台上的单片插入成为可能。在该项目中，将对其中两个分别基于InP和Si的1.3或1.5 μm工作波长进行演示。虽然PIC代工厂依赖于特定和独立的技术，但由于功能材料的普遍集成，我们的解决方案将绕过这些特殊性。此外，我们的跨学科方法基于对真实的世界需求的分析，与最终用户、工业和社会利益相关者共同制定开发路线图，为扩大我们的技术开发规模以改善社会做好准备。为了实现这些目标，我们的九个合作伙伴组成的联盟涵盖了材料科学，光子学，等离子体，PIC技术和社会科学的能力，其中包括两家中小企业。

The new technology envisioned in CIRCULIGHT will establish a breakthrough in Photonic Integrated Circuit (PIC) capabilities, withimpact across a wide range of applications of high economic and societal value. It will lay the foundations of a new class of PICswhich are highly functional, miniaturized and low power-consuming, as well as being manufacturable at low cost, thereby contributing significantly to environmental protection and related quality of life. The essential building block that will be created in this project is a truly integrated optical circulator, which protects active and passive integrated functions from each other, distributes light between them, and finally allows very large scale integration of photonic components within diversified PIC architectures. The practical realization of such a structure will be a world-first and a breakthrough in PIC technology. CIRCULIGHT technological decisive progress is based on magneto-optical (MO) nanoparticle-composite sol-gel material and on magneto-biplasmonic (MBP) effect, which will enable the monolithic insertion of circulators on any photonic platform. Within the project, a demonstration will be made on two of them, based on InP and Si respectively, operating at 1.3 or 1.5 µm. While PIC foundries rely on specific and independent technologies, our solution will bypass these specificities, thanks to a universal integration of functional materials. In addition, our interdisciplinary approach is based on the analysis of real world needs, feeding the co-creation of an exploitation roadmap together with end users, industrial and societal stakeholders, in preparation for the scaling up of our technology developments to transform society for the better. To reach these objectives, our consortium of nine partners encompasses competencies in material sciences, photonics, plasmonics, PICs technology and social science, and includes two SMEs.
