Integrated Optical Sciences
Biomolecules and nanostructures
The Optical Sciences group studies the interaction of light and matter. Our current focus is on detection and sensing/imaging with an emphasis on the development of integrated photonics. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
A Poormans Superlens for Visible Light
We try to realize and test the first superlens for visible light. Its predicted imaging properties will be addressed with a combination of single molecule detection and near-field optics. The object that is to be imaged is a subwavelength aperture. Single molecules at the other side of the film will report on the local fields built-up by the lens. Their fluorescence intensity will reveal not only the magnitude of the electric field but also its direction. Variation of the relative position of object and detector (single molecule) will expose the imaging properties of the poormans superlens.
