    • All-fiber all-normal dispersion laser with a fiber-based Lyot filter 

      Özgören, K.; Ilday, F. Ö. (Optical Society of America, 2010-04-15)
      We propose the use of a short section of polarization-maintaining fiber as a birefringent medium to construct an all-fiber Lyot filter inside the cavity of a fiber laser. This allows mode-locked operation of an all-fiber ...
    • Broadband terahertz modulators using self-gated graphene capacitors 

      Kakenov, N.; Balci, O.; Polat, E. O.; Altan, H.; Kocabas, C. (Optical Society of America, 2015)
      We demonstrate a terahertz intensity modulator using a graphene supercapacitor which consists of two large-area graphene electrodes and an electrolyte medium. The mutual electrolyte gating between the graphene electrodes ...
    • Generation of soliton molecules with independently evolving phase in a mode-locked fiber laser 

      Ortaç, Bülend; Zaviyalov, A.; Nielsen, C.K.; Egorov, O.; Iliew, R.; Limpert, J.; Lederer, F.; Tünnermann, A. (Optical Society of America, 2010)
      We report the experimental generation of two-soliton molecules in an ytterbium-doped fiber laser. These molecules exhibit an independently evolving phase and are characterized by a regular spectral modulation pattern with ...
    • Graphene mode-locked Cr:LiSAF laser at 850 nm 

      Canbaz F.; Kakenov, N.; Kocabas, C.; Demirbas, U.; Sennaroglu, A. (OSA - The Optical Society, 2015)
      We report, for the first time to our knowledge, a mode-locked femtosecond Cr:LiSAF laser initiated with a high-quality monolayer graphene saturable absorber (GSA), synthesized by chemical-vapor deposition. The tight-focusing ...
    • Observation of soliton molecules with independently evolving phase in a mode-locked fiber laser 

      Ortaç, B.; Zaviyalov, A.; Nielsen, C.K.; Egorov O.; Iliew, R.; Limpert J.; Lederer F.; Tünnermann, A. (2010)
      We report the experimental generation of two-soliton molecules in an all-polarization-maintaining ytterbium-doped fiber laser operating in the normal dispersion regime. These molecules exhibit an independently evolving ...
    • Properties of a microjoule-class fiber oscillator mode-locked with a SESAM 

      Lecaplain, C.; Ortac, Bülend; MacHinet G.; Boullet J.; Baumgartl, M.; Schreiber, T.; Cormier, E.; Hideur, A. (IEEE, 2011)
      Energy scaling of ultrafast Yb-doped fiber oscillators has experienced rapid progress largely driven by many applications that require high average power femtosecond pulses. The fundamental challenge for ultrafast fiber ...
