    • Advances in femtosecond single-crystal sum-frequency generating optical parametric oscillators 

      Köprülü, K, G.; Kartaloğlu, T; Dikmelik, y.; Aytür, O. (IEEE, Piscataway, NJ, United States, 1998)
      The effect of compensating the group velocity mismatch between the orthogonal pump components on the conversion efficiency of the optical parametric oscillators (OPOs) was investigated. A femtosecond single-crystal ...
    • Femtosecond self-doubling optical parametric oscillator based on KTiOAsO4 

      Kartaloğlu, T.; Aytür, O. (IEEE, 2003)
      We report a femtosecond intracavity-frequency-doubled optical parametric oscillator that employs a single KTiOAsO4 crystal for both parametric generation and frequency doubling. This device generates a yellow output beam ...
    • Idler-efficiency-enhanced long-wave infrared beam generation using aperiodic orientation-patterned GaAs gratings 

      Figen, Z. G.; Aytür, O.; Arıkan, O. (Optical Society of America, 2016)
      In this paper, we design aperiodic gratings based on orientation-patterned gallium arsenide (OP-GaAs) for converting 2.1 μm pump laser radiation into long-wave infrared (8-12 μm) in an idler-efficiency-enhanced scheme. ...
    • Multimode pumping of optical parametric oscillators 

      Marshall, L. R.; Kaz, A.; Aytur, O. (Institute of Electrical and Electronics Engineers, 1996-02)
      Calculations suggest that optical parametric oscillators (OPO's) can be efficiently pumped using multimode, divergent pump sources. The influence of pump beam divergence and mode structure upon OPO performance is measured ...
    • Performance analysis of an optical packet switch employing full/limited range share per node wavelength conversion 

      Akar, N.; Karasan, E.; Muretto G.; Raffaelli, C. (2007)
      In this paper, we study an asynchronous optical packet switching node equipped with a number of limited range or full range wavelength converters shared per node. The packet traffic is realistically modeled by a superposition ...
    • Performance of WDM transport networks 

      Karasan, E.; Ayanoglu, E. (Institute of Electrical and Electronics Engineers, 1998-08)
      Wavelength division multiplexed point-to-point transport is becoming commonplace in wide area networks. With the expectation that the next step is end-to-end networking of wavelengths (in the optical domain without conversion ...
    • Plane-wave dynamics of optical parametric oscillation with simultaneous sum-frequency generation 

      Dikmelik, Y.; Akgün, G.; Aytür, O. (Institute of Electrical and Electronics Engineers, 1999-06)
      This paper presents a theoretical analysis of sum-frequency generating optical parametric oscillators where a single nonlinear crystal is used for both parametric generation and sum-frequency generation. In these devices, ...
    • Plane-wave dynamics of optical parametric oscillation with simultaneous sum-frequency generation 

      Akgun Gulbin, Dikmelik Yamac, Aytur Orhan (IEEE, Piscataway, NJ, United States, 1998)
      The plane wave dynamics of a single-crystal upconversion optical parametric oscillators (OPO) with simultaneous sum-frequency generation (SFG) was studied. It was presumed that simultaneous phase-matching of the SFG and ...
