High quality nanomechanical resonators exploiting the effects of electromagnetic radiation pressure have a broad range of applications ranging from metrology and sensing to information processing. During her studies, Bhagya Nair has investigated integrated arrays of silicon nitride nano-membranes whose vibrations can be activated by optical fields. Methods for assembling and characterizing the optomechanical properties of highly parallel arrays of such membranes or improving their reflectivity using electron beam lithography techniques have been developed.

The results are promising for future fundamental investigations of collective optomechanical phenomena or for the practical realization of high-quality sensors or telecommunication components.

The PhD degree was completed at the Department of Physics and Astronomy, Science and Technology, Aarhus University.
