Surface Plasmon Polaritons Probed with Cold Atoms
We report on an optical mirror for cold rubidium atoms based on a repulsive dipole potential created by means of a modified recordable digital versatile disc. Using the mirror, we have determined the absolute value of the surface plasmon polariton (SPP) intensity, reaching 90 times the intensity of the excitation laser beam. Furthermore, we have also directly measured thermo-plasmonic effects accompanying SPPs excitation on gold submicron structures.

Part of the equipment was purchased thanks to the financial support of the European Regional Development Fund in the framework of the Polish Innovation Economy Operational Program (POIG.02.02.00-00-003/08) and Ministry of Science and Higher Education (7150/E-338/M/2016). We are grateful to Bartosz Such and Marta Targosz-Korecka for the help with the AFM microsope and Agnieszka Szybowska and Marek Gołąb for lending us the infrared camera.
