Project Block C

Projektbereich C

C01 - Micro- and nano-optical sensors

 

Supervisor:

Prof. Zappe

Researcher:

Stanislav Sherman

Duration:

2013-2016

Funded by:

DFG

Brief description:

The goal of this project is the realization of a distributed temperature sensor array, including components for excitation and detection, as well as the development of an adapted signal processing for the entire foil and its evaluation on sample applications.

C02 - Planar integrated sensor arrays

 

Supervisor:

Prof. Reithmeier und Prof. Roth

Researcher:

Christian Kelb

Duration:

2013-2016

Funded by:

DFG

Brief description:

The subproject C02 explores novel polymer-based sensor structures for optical strain-measurement, in terms of different sensor types as well as in terms of different manufacturing processes. In the long run, all approaches aim at a large-scale and a low-cost manufacturing process (e.g., roll-to-roll). The goal is the integration of sensor systems on polymer foils, which convert strain amplitude and direction into optical signals, enabling a wide range of applications. The main challenge lays in the implementation of strain sensors, which are based on intensity- and spectral-modulation, the study of parasitic effects and the development of calibration concepts as well as advancing lab-typical production processes to large-scale processes.

C03 - Planar-optical polymer foil spectrometer

 

Supervisor:

Prof. Schade

Researcher:

Rozalia Orghici

Duration:

2013-2016

Funded by:

DFG

Brief description:

In the subproject C03 wavelength-dispersive planar optical elements, in particular, arrayed waveguide gratings will be investigated. The aim is to provide a polymer film spectrometer, which can be tailored to the requirements of the other Sensor technology projects regarding wavelength range and resolution. A particular challenge is the achievement of a sufficient decoupling from external influences, such as temperature and mechanical stress. The approach taken here is the implementation of ZnO nanowires to locally modify thermo-optical and mechanical properties of the polymer film.

C04 - Resonate and interferometric optical sensors

 

Supervisor:

Prof. Zappe und Dr. Willer

Researcher:

Meike Hofmann, Elke Pichler and Yanfen Xiao

Duration:

2013-2016

Funded by:

DFG

Brief description:

The objective of sub-project C04 is the development of waveguide-based structures in polymer foils for application as selective chemical sensors. We follow two approaches: ring resonators and Mach-Zehnder interferometers (MZI). In both cases, the core of a monomode waveguide is functionalized with gas-sensitive layers. Thus, the effective refractive index is changed if an analyte adsorbs onto it, leading to a shift of the resonance wavelength or a change in the interference pattern, respectively.

C05 - Flüstergalerie-Resonatoren zur molekularen Analytik

 

Supervisor:

Prof. Morgner and Dr. Wollweber

Researcher:

Ann Britt Petermann

Duration:

2013-2016

Funded by:

DFG

Brief description:

As part of the subproject C05 polymer-based sensors should be developed for the life sciences. These sensors are supposed to enable the optical and spectroscopic analytics in fluidic systems. The target of the first conveyor section is to design a sensor, which is able to detect lowest analytic concentrations (final target single-molecule sensitivity). Operating principle of the sensor are Whispering gallery resonances in microspheres.
