Compact Birefringent Waveplates Photo-Induced in Silica by Femtosecond Laser

  • Matthieu Lancry,
  • Rudy Desmarchelier,
  • Kevin Cook,
  • Bertrand Poumellec and
  • John Canning

30 September 2014

Recently, we showed that femtosecond laser induced “nanogratings” consist of thin regions with a low refractive index (Δn = −0.15), due to the formation of nanoporous silica surrounded by regions with a positive index change. In this paper, we invest...
