Dear Students
This is the announcement for the lecture “NanoOptics” in the winter term 24/25 at TU Dresden. The lecture will take place on-site on Monday’s always at 1 p.m. in the REC/B214 lecture hall.
NanoOptics (N-Optics) describes optical phenomena occurring on the length scale below the diffraction limit of approximately half the wavelength. Optical interaction between fluorescent molecules, between molecules and a metallic or dielectric surface such as a nanoparticle, or the effect of surface enhanced Raman scattering used for nanoscale surface analysis, all base on this optical far- and near-field coupling effects. As such, nanooptics has the power of providing optical characterization down to the 1-nm length scale, thus being applicable to many new fields and nanodevices, such as 2D materials, nanostructured systems, or local defects. Of importance, however, is the understanding and interplay of different physical effects such as damping, electric field enhancement, radiative and non-radiative transitions, and others more. This lecture will provide the necessary background, as well as the view into prospective applications.

Optical interaction between fluorescent molecules, between molecules and a metallic (plasmonic) or dielectric (phononic) surface, between nanoparticles, or the effect of surface enhanced Raman scattering used for nanoscale surface analysis, all base on these optical far- and near-field coupling effects. As such, nanooptics has the power of providing optical characterization on the 10-nm length scale, thus being applicable Ito many novel fields and nanodevices.
