The ATONAL project aims at developing micro- and nano-structured functional systems that can be opticallytuned, by exploiting the photoswitching properties of materials containing photochromic molecules such asazobenzene derivatives. In recent years, new approaches have emerged, in the field of information andcommunication technologies, based on the development of micro- and nano-structured devices (for integratedoptics, efficient light sources...) or on the use of innovative media and materials (flexible electronics, organicoptoelectronic...).These approaches have been made possible by the technological developments that now allow matterprocessing 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 incorporatingphotochromic materials for the elaboration of optically tunable devices in biomedical applications.Materials incorporating azobenzene derivatives exhibit quite unique photomechanical responses in addition totheir photochromic properties. These deformations are directed by the light polarization and may manifest atdifferent scales. Coupling these compounds with other functional materials may then be envisaged as a routefor 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 withusual integrated optical devices (for telecommunication application), fabricated with standard silicontechnologies. We will consider devices such as ring resonators, couplers, filters and gratings, the operation ofwhich critically depends on their structure. We will then characterize the control of their functioning conferredby the photoactive material. Finally, in collaboration with the companies supporting the project, we willexplore the possibility to implement this approach into real-world devices.

ATONAL项目旨在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，开发可光调谐的微纳米结构功能系统。近年来，在信息和通信技术领域，基于微纳米结构器件（用于集成光学，高效光源…）的发展或基于创新媒体和材料（柔性电子，有机光电…）的使用，出现了新的方法。技术的发展使这些方法成为可能，现在可以将物质处理缩小到最终规模，并在同一建筑中集成不同的材料。在这种情况下，ATONAL项目的主要目标是研究混合结构和光致变色材料在生物医学应用中光学可调谐器件的潜力。含偶氮苯衍生物的材料除了具有光致变色性质外，还表现出相当独特的光力学响应。这些变形是由光偏振引导的，可以在不同的尺度上表现出来。然后可以设想将这些化合物与其他功能材料偶联，作为开发可以通过光学刺激来驱动、调谐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，将光敏杂化材料层与通常的集成光学器件（用于电信应用）耦合，用标准硅技术制造。我们将考虑环形谐振器、耦合器、滤波器和光栅等器件，它们的操作严重依赖于它们的结构。然后我们将描述光活性材料对其功能的控制。最后，通过与支持该项目的公司合作，我们将探索将这种方法应用于现实世界设备的可能性。
