Coherent Optics and Nanophotonics
The Coherent Optics group researches innovative approaches to both measurement and synthesis of lightwave fields. A key motivation here is the development of robust and at the same time precise methods for wave field detection, which form the basis for industrial measurement systems for three-dimensional shape and deformation measurement. Due to the use of structures that are significantly smaller than the wavelength of the light to be influenced, micro- or nano-optical components and systems open up possibilities in the design of optical systems that cannot be realized with conventional optical components such as lens systems. Structuring options on the order of 10 to 100 nm open up new fields of application not only for the miniaturization of optical components, but also for new concepts in the design of wave fields for tasks in the field of measurement technology and sensors and for security features and measures against counterfeiting of industrial products or for consumer products such as lighting technology. One therefore speaks of "tailored light". The combination of these possibilities with the competence of wave field simulation and the design of optical systems in the field of coherent optics at BIAS enables the implementation of corresponding systems in addition to the calculation of such structures.
