A. Characterization

Near Field Scanning Optical Microscopy (Alpha300 S System)

Operating modes:

  • Near field optical microscopy: transmission, reflection, collection, fluorescence:
    • Near field characterization of  photonic devices (waveguides, photonic crystals, plasmonic systems)
    • Characterization of active devices
    • Imaging of biological systems with subwavelength resolution
    • Fluorescence measurements
  • Confocal microscopy: transmission, reflection, fluorescence:
    • Characterization and imaging of biological and polymer samples with diffraction limited resolution
  • Atomic force microscopy: contact and AC – Mode

Applications:

  • imaging the optical properties of a sample with resolution below the diffraction limit with applications in nanotechnology, nanophotonics, nanooptics and plasmonics;
  • Materials research and polymers;
  • Single  molecule detection;
  • Life sciences;
  • Fluorescence characterizations;

Characterization of photonic devices and microoptical systems

  • Experimental setup for measuring the spectral characteristic of photonic devices operating at 1550 nm.
  • Characterization of microoptical components at various wavelengths in visible and infrared

 OPTOLAB laboratory

OPTOLAB is a laboratory for studying and testing of optical and structural properties of thin mono- and multi layers and bulk organic/anorganic  materials. The laboratory will be certified to ISO 17025:2005 standard for thin films measurements. The OPTOLAB  facilities consist of high  performance  spectroscopic ellipsometer, SE 800 XUV from SENTECH, high resolution Raman spectrometer, LabRAM HR from HORIBA Jobin Yvon and spectrophotometer for UV_VIS_NIR and IR spectral range from Carl Zeiss Jena.

(i) Ellipsometric measurement of nanometric films -  analysis and characterization of the nanometric thin films, interfaces, multi  layer structuresfrom different materials - dielectrics, conductive oxides, polymers, emiconductors. Measuring the index of refraction (n) and the extinction coefficient (k) for a  single layer permits one to determine the material composition and modeling of optical  performance.

Contact person: Dr. Munizer Purica; Florin Comanescu

(ii) Testing the optical properties of samples for the ability to reflect or transmit light by spectrophotometric measurements - thin films characterization by recording the transmistance, absorbance spectra [T(λ), A(λ)] used for  optical coatings; surface reflectivity characterization of the texturized and porosified surfaces, material properties: the absorption coefficient and the bandgap for the semiconductor and dielectric films obtained by processing of T(λ) and R(λ).

 Contact person: Dr. Munizer Purica, Elena Budianu

(iii) Raman spectroscopy for physical and chemical material analysis of solids, liquids and solutions for chemical identification, characterization of molecular structures; composition and phase (crystalline/amorphous) of composites materials (compound semiconductors,  oxidic semiconductors); polymers characterizations and polimer nanocomposites; chemical and biological detection using SERS technique; micro/nano structures characterization (micro/nanorods,  carbon nanotubes), self assembled molecule (SAM) on functionalized substrate and other.
