The Semiconductor Nanophotonics
lab at the Eindhoven University of Technology (The Netherlands) has an open PhD student position on nanophotonic lab-on-fiber sensing.Background: Lab-on-fiber sensing
Optical fibers carry optical signals over large distances and are widely used for communications. They are also increasingly used for sensing, as they allow gathering information from environments which are far or hard to reach (from arteries to dikes). Fiber sensors are compact, minimally-invasive and potentially inexpensive. However, the applications have so far mostly be limited to temperature and pressure/strain sensing. By building a sensor on the tip of the fiber and properly functionalizing it, it is in principle possible to sense all physical, chemical and biological properties of the environment, turning the fiber into a powerful sensing instrument. This 'lab-on-fiber' technology has so far been hampered by the difficulty of realizing the sensors on the tiny fiber tips. Our group has recently demonstrated a method to fabricate sensors and photonic circuits on a semiconductor wafer and transfer them to a fiber tip. This allows harnessing the power of integrated photonics to build complex sensing structures on fiber tips and opens the way to a new generation of fiber sensors.Project description
The selected candidate will perform applied research in integrated photonics and optical sensing. He/she will conceive, realize and characterize nanophotonic devices and circuits on fiber tips, and test their application in different sensing problems, including sensing of molecular biomarkers.
The project will be supervised by Prof. A. Fiore and co-supervised by Dr. P. Zijlstra at TU/e. A close collaboration is foreseen with the partners of a Dutch-Taiwanese consortium, including research visits to Taiwan. The PhD student will be integrated in a young, dynamic and highly collaborative team active in this area.
