Photonics is the science of generating, controlling and detecting light. The field is at the crossroads of several disciplines including physics, biology, materials, mathematics and chemistry. Following the rapid evolution of electronics subsequent to the invention of the transistor in the late 1940's, the coming decades will see photonics impact most areas of our lives including future internet infrastructure, advanced manufacturing, radical new approaches to Healthcare, Lighting and enabling a revolution in sensing and imaging. However, convention teaches us that focussing of light is constrained by the Abbé diffraction limit, that light penetrates tissue poorly due to Rayleigh and Mie scattering and that collimated, coherent light emission requires a laser. By challenging such established conventions with a transformative understanding of the fundamentals of light propagation, we can create a paradigm shift; while the 20th century was the century of the electron, we firmly believe that the 21st will be the century of the photon. In order to realize this vision, we need to explore the fundamental concepts of coherently shaping light in phase, amplitude and polarization - structuring light - to unveil startling advances. In particular, the structuring and shaping of light will break through perceived limits and open up the next generation of opportunities, particularly in the burgeoning areas of healthcare and biophotonics.Four projects will run in parallel and by combining their outputs, we aim to overcome current limits in Photonics and address major Challenges such as super-resolution microscopy, nanoscopic sensing, single cell proteomics, ubiquitous laser-like sources, spatially controlled optogenetics, therapy and imaging at depth

光子学是一门产生、控制和探测光的科学。该领域处于包括物理学、生物学、材料学、数学和化学在内的几个学科的交叉点。继20世纪40年代后期晶体管发明之后，电子产品迅速发展，未来几十年将看到光子学影响我们生活的大部分领域，包括未来的互联网基础设施、先进制造业、医疗保健、照明的激进新方法，以及传感和成像的革命。然而，传统告诉我们，光的聚焦受到abb<s:1>衍射极限的限制，由于瑞利散射和米氏散射，光穿透组织的能力很差，而准直的、相干的光发射需要激光。通过对光传播基本原理的变革性理解来挑战这些既定的惯例，我们可以创造一个范式转变；如果说20世纪是电子的世纪，那么我们坚信21世纪将是光子的世纪。为了实现这一愿景，我们需要探索在相位、振幅和偏振上相干整形光的基本概念——结构光——以揭示惊人的进展。特别是，光的结构和形状将突破已知的限制，开辟下一代的机会，特别是在新兴的医疗保健和生物光子学领域。四个项目将并行运行，通过结合他们的产出，我们的目标是克服当前光子学的限制，并解决诸如超分辨率显微镜、纳米传感、单细胞蛋白质组学、无处不在的激光源、空间控制光遗传学、治疗和深度成像等主要挑战
