About us
The Laboratory of Photonic and Plasmonic Nanostructures (LPPN) of the Information Optics Department conducts research in the field of photonics, plasmonics, functional materials and super-resolution imaging. The works concern, among other things, modelling, production and characterization of planar as well as micro- and nanostructured resonance materials enabling basic research in the field of linear and non-linear effects of strong interactions of light with matter at the nanoscale. The results find applications in the design of all-optically controlled systems for the needs of telecommunications, ultra-sensitive detectors, enabling study of interactions of single biological molecules, or improvements of the efficiency of photovoltaic systems. The LPPN has developed, among other things, the technology of producing ultra-smooth silver layers for applications in plasmonic systems, sub-wavelength plasmonic lenses and high resolution probes for scanning near-field optical microscopy (SNOM).
LPPN is equipped with the following laboratory infrastructure:
- a station for the production of multilayer functional metallic and dielectric materials, the main element of which is a Lesker PVD-75 sprayer with an electron beam and an ion gun,
- a station for the characterization of morphological and material properties of the produced nanostructures, consisting of: a) a Zeiss Sigma electron microscope with SE, BSE and In-Lens detectors with elemental composition analysis; b) a VECCO WYKO NT2200 contactless optical profilometer, an atomic force scanning microscope (NT-MDT) and a scanning tunnelling microscope (NT-MDT),
- a station for the characterization of linear optical properties, including white light diodes, a spectrometer (Ocean Optics with a CCD linear detector), near field scanning optical microscope (NT-MDT) and an optical microscope (Olympus).
