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).

我们的研究团队制造光谱仪、光纤探头、折射仪以及用于光吸收、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)被测变量的绝对量化，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、成像和传感领域的商业发展进步。在开发仪器时，我们制造原型，编写自己的软件，并经常设计自己的电子电路。 最重要的是，新的和更好的仪器使我们能够发现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，还产生了29篇研究论文，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，然后与工业界和学术界的合作者合作进行进一步开发。这使我们的研究产生了最大的影响，并为HQP提供了建立工业和学术联系国际网络的机会。 该应用程序中的主题分为四个类别，涵盖仪器设计，基础光学，光谱学，光化学和微量分析化学。在项目套件（1）中，我们将为分析光谱学中的新光源开发几个应用。该光源基于多路复用分立固态光源或MEMS器件。在其他项目套件中，我们将（2）推进使用光学微腔进行化学传感，（3）使用非常敏感的光纤法布里-珀罗腔进行振幅超过5个数量级和频率超过6个数量级的声音测量，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，我们将提供培训和教育，至少4博士候选人（每年2-3），6硕士。候选人（每年2人），2名博士后研究员（每年1名），和至少5名本科生（1 p.a.）。研究生和本科生通过项目管理，预算编制，本科生招聘和实习与合作实验室，如工业合作伙伴（如ABB加拿大，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）参与发展的各个阶段。
