The ATONAL project aims at developing micro- and nano-structured functional systems that can be optically**tuned, by exploiting the photoswitching properties of materials containing photochromic molecules such as**azobenzene derivatives. In recent years, new approaches have emerged, in the field of information and**communication technologies, based on the development of micro- and nano-structured devices (for integrated**optics, efficient light sources...) or on the use of innovative media and materials (flexible electronics, organic**optoelectronic...).**These approaches have been made possible by the technological developments that now allow matter**processing down to ultimate scales and integration of different materials in a same architecture. In this context,**the main objective of the ATONAL project is to investigate the potentiality of hybrid structures incorporating**photochromic materials for the elaboration of optically tunable devices in biomedical applications.**Materials incorporating azobenzene derivatives exhibit quite unique photomechanical responses in addition to**their photochromic properties. These deformations are directed by the light polarization and may manifest at**different scales. Coupling these compounds with other functional materials may then be envisaged as a route**for developing structures and devices that can be actuated, tuned or reconfigured by means of optical stimuli.**As a proof of concept, we will first develop simple processes to couple photoactive hybrid material layers with**usual integrated optical devices (for telecommunication application), fabricated with standard silicon**technologies. We will consider devices such as ring resonators, couplers, filters and gratings, the operation of**which critically depends on their structure. We will then characterize the control of their functioning conferred**by the photoactive material. Finally, in collaboration with the companies supporting the project, we will**explore the possibility to implement this approach into real-world devices.**

ATONAL项目旨在开发可通过利用含有光致变色分子（如偶氮苯衍生物）的材料的光开关特性进行光学调谐的微米和纳米结构功能系统。近年来，在信息和通信技术领域，基于微结构和纳米结构器件的发展（用于集成光学器件、高效光源等），出现了新的方法。或使用创新的媒介和材料（柔性电子、有机 ** 光电子.）。技术的发展使这些方法成为可能，现在允许物质处理到最终的规模，并将不同的材料集成在同一个架构中。在这种情况下，** ATONAL项目的主要目标是研究混合结构的潜力，将 ** 光致变色材料用于生物医学应用中的光学可调器件的制作。偶氮苯衍生物材料除了具有光致变色性能外，还表现出独特的光机械响应。这些变形是由光偏振引导的，并且可以在不同的尺度上表现出来。然后，将这些化合物与其他功能材料结合，可以设想为开发可以通过光学刺激驱动、调节或重新配置的结构和设备的途径。作为概念验证，我们将首先开发简单的工艺，将光敏混合材料层与标准硅技术制造的常规集成光学器件（用于电信应用）耦合。我们将考虑诸如环形谐振器、耦合器、滤波器和光栅等器件，** 的操作关键取决于它们的结构。然后，我们将表征由光活性材料赋予它们的功能的控制。最后，我们将与支持该项目的公司合作，探索将这种方法应用到实际设备中的可能性。
