    • 10-W, 156-MHz all-fiber-integrated Er-Yb-doped fiber laser-amplifier system 

      Pavlov, Ihor; İlbey, Emrah; Dülgergil, Ebru; İlday, Fatih Ömer (Optical Society of America, 2012)
      We demonstrate all-fiber, high-power chirped-pulse-amplifier system, operating at 1550 nm. 156-MHz soliton oscillator seeds a two-stage single-mode amplifier with output power of 10 W. After external compression, pulse ...
    • Dipole antenna couplers for subwavelength metal-insulator-metal waveguides 

      Onbasli, M.C.; Okyay, Ali K. (Optical Society of America, 2010)
      Near-infrared light (λ=1550 nm) was coupled into a 100-nm-core Ag/SiO2/Ag waveguide using dipole antennas. We demonstrate that using antennas, the field intensity inside the waveguide can be enhanced by changing the antenna ...
    • High efficiency monolithic photodetectors for integrated optoelectronics in the near infrared 

      Okyay, Ali K.; Onbaşlı, M. Cengiz; Ercan, Burcu; Yu H.-Y.; Ren, S.; Miller, D.A.B.; Saraswat, K.C.; Nayfeh, A.M. (IEEE, 2009)
      Monolithic Germanium photodetectors integrated on Si with external efficiency up to 68% at 1550nm and low dark current density 3.2mA/cm2 are demonstrated. The absorption edge red shifted by 47nm corresponding to bandgap ...
    • Nonlinear chirped-pulse amplification of a soliton-similariton laser to ~1 µJ at 1550 nm 

      İlbey, Emrah; Pavlov, Ihor; Dülgergil, E.; Öktem, Bülent; Yavas, Seydi; Rybak, Andrii; Zhang, Zuxing; İlday, Fatih Ömer (Optical Society of America, 2012)
      We demonstrate all-fiber-integrated nonlinear CPA system operating at 1550 nm, seeded by a soliton-similariton laser. Chirped 2-μJ pulses are compressed to 700-fs, 0.5-μJ pulses at 1 MHz. Amplifier output is through a ...
