Fresnel Fiber Optica Tweezers


  • 3D printed Fresnel lenses
  • Very efficient trapping (Pmin = 200 µW)
  • Large fiber-to-fiber distance (d = 200 µm)



  • Polarization resolved spectroscopy on trappen NaYF4:Eu3+ nanorods


  • Stable optical trapping
  • Determination of σ and π orientation of selected electric and magnetic dipole transitions
  • Determination of nanorod orientation by spectroscopic means only



  • Spectroscopy of trappen NaYF4:Er3+ nanorods


  • Trapping with fiber tips
  • Emission specroscopy in 3 orthogonal directions
  • Emission recording with spatial resulution
