Quantum-enhanced multiphoton fluorescence microscopy

该项目旨在建立一种新型的多光子荧光显微镜，依靠光的量子态来克服当前技术的灵敏度限制。学生将开发和制造合适的量子光源，将多光子吸收增强到可以使用较低激光功率激发荧光的水平，这非常适合生物样品。它将包括非线性光学和量子光学以及成像的组合。这名博士生将致力于光学系统的设计和实现、非线性频率转换、量子态(例如纠缠光子)的产生和表征、软件编码和显微镜。他们将可以使用最先进的光学实验室、激光光源和光子探测器。还将研究用于构建更紧凑和面向应用的系统的纠缠光子的芯片来源。该奖学金由位于英国格拉斯哥的弗劳恩霍夫应用光子学中心(https://www.cap.fraunhofer.co.uk)，)共同资助，旨在帮助他们访问其原型设施，并促进与技术用户的协作工作。

The project aims at building a novel multiphoton fluorescence microscope that relies on quantum states of light to overcome the sensitivity limits of the current technology. The student will develop and build the appropriate quantum light source for enhancing multiphoton absorption to levels where fluorescence can be excited using lower laser power, ideally suited for biological samples. It will encompass a combination of nonlinear and quantum optics, as well as imaging. The PhD student will work on the design and realisation of optical systems, nonlinear frequency conversion, the generation and characterisation of quantum states (e.g. entangled photons), software coding and microscopy. They will have access to state-of-the-art optical laboratories, laser sources and photon detectors. On-chip sources of entangled photons for building more compact and application-oriented systems will also be investigated. The studentship is co-funded by Fraunhofer Centre for Applied Photonics, Glasgow, UK (https://www.cap.fraunhofer.co.uk), giving access to their prototyping facilities and promoting collaborative work with technology users.
