"Plasmonic local density of states in the quantum regime"

Abstract

In this Talk we will introduce the concept of local density of states (LDOS) associated with propagative surface plasmons (SPs). We will demonstrate how a near field scanning optical microscope (NSOM) coupled to a leakage radiation microscope (LRM) can be used for mapping such LDOS in a plasmonic planar device. We will show how to apply this method with a nitrogen vacancy (NV) based NSOM working in the quantum regime. Then we will apply this method to the development and optimization of a planar SP device working as a plasmonic collimator. We will compare this approach to other LDOS measurments of plasmonic observable with NSOM realized recently by our group.
