Our research group builds spectrometers, fiber probes, refractometers, as well as micro-sensors for optical absorption, fluorescence, mechanical strain, vibration and sound. In our instrument development we are guided by two principles:       (A) absolute quantification of the measurand, but avoiding light intensity measurements       (B) emphasis on small volumes and/or low concentrations We take full advantage of the advances of the commercial developments in the telecom, imaging and sensing areas. When developing instruments we fabricate prototypes, write our own software and frequently design our own electronic circuitry. Most importantly for the proposed program, new and better instruments allow us to make discoveries that would not be observable with conventional tools. In the past 6 years, our work therefore produced not only 3 patents but also 29 research articles, including 8 cover articles. In all research programs, we first build in-house expertise and then work with collaborators in industry and academia on further development. This gives our research the largest impact and provides HQP with an opportunity to build an international network of industrial and academic contacts. The topics in this application fall into four categories spanning instrument design, fundamental optics, spectroscopy, photochemistry and micro-analytical chemistry. In project suite (1) we will develop several applications for a new light source in analytical spectroscopy. This light source is based on multiplexing either discrete solid state light sources or MEMS devices. In other project suites we will (2) advance the use of optical micro-cavities for chemical sensing, (3) use an extraordinarily sensitive fiber Fabry-Perot cavity for sound measurements over 5 orders of magnitude in amplitude and 6 orders of magnitude in frequency, and (4) exploit properties of photonic crystal waveguides for both precision optical measurements and separation science. In the next 5 years we will provide training and education to at least 4 PhD candidates (2-3 per annum), 6 MSc. candidates (2 p.a.), 2 postdoctoral fellows (1 p.a.), and at least 5 undergraduate students (1 p.a.). Graduate students and undergraduate students are involved at all stages of development through project management, budgeting, hiring of undergraduates and internships in with collaborator labs, e.g. industrial partners (e.g. ABB Canada, GasTOPS, KPM, Aurubis) or academic research labs (INO Naples, KGH Stockholm, innoFSPEC Potsdam).

我们的研究小组制造光谱仪、光纤探头、折射计以及用于光吸收、荧光、机械应变、振动和声音的微型传感器。在我们的仪器开发中，我们遵循两个原则：(A)绝对量化被测量，但避免光强度测量；(B)强调小体积和/或低浓度我们充分利用电信、成像和传感领域商业发展的进步。在开发仪器时，我们制造原型，编写我们自己的软件，并经常设计我们自己的电子电路。对于拟议的计划来说，最重要的是，新的、更好的仪器使我们能够做出传统工具无法观察到的发现。在过去的6年里，我们的工作不仅产生了3项专利，而且还产生了29篇研究文章，其中包括8篇封面文章。在所有研究项目中，我们首先建立内部专业知识，然后与行业和学术界的合作者合作，进一步发展。这给我们的研究带来了最大的影响，并为HQP提供了一个建立国际产业界和学术界联系网络的机会。这项应用的主题分为四类，横跨仪器设计、基础光学、光谱学、光化学和微分析化学。在项目套件(1)中，我们将为分析光谱分析中的新光源开发几种应用。该光源基于对分立固态光源或MEMS器件的多路复用。在其他项目中，我们将(2)将光学微腔用于化学传感，(3)使用非常灵敏的光纤法布里-珀罗腔来测量幅度超过5个数量级、频率超过6个数量级的声音，以及(4)利用光子晶体波导的特性进行精密光学测量和分离科学。在未来5年内，我们将为至少4名博士生(每年2-3名)、6名硕士提供培训和教育。候选人(每年2人)，博士后研究员2人(每年1人)，以及至少5名本科生(每年1人)。研究生和本科生通过项目管理、预算编制、本科生招聘和与合作实验室的实习参与到发展的所有阶段，例如工业合作伙伴(如ABB Canada、GasTOPS、KPM、Aurubis)或学术研究实验室(INO那不勒斯、KGH斯德哥尔摩、InnoFSPEC波茨坦)。
