    • Characterization of thermally poled germanosilicate thin films 

      Ozean, A.; Digonnet, M.J.F.; Kino G.S.; Ay F.; Aydinli, A. (Optical Society of American (OSA), 2004)
      We report measurements of the nonlinearity profile of thermally poled low-loss germanosilicate films deposited on fused-silica substrates by PECVD, of interest as potential electro-optic devices. The profiles of films grown ...
    • Compact optical temporal processors 

      Mendlovic, D.; Melamed, O.; Ozaktas, H. M. (Optical Society of America, 1995)
      Optical signal processing can be done with time-lens devices. A temporal processor based on chirp-z transformers is suggested. This configuration is more compact than a conventional 4-f temporal processor. On the basis of ...
    • Linear electro-optic coefficient in multilayer self-organized InAs quantum dot structures 

      Akca, B.I.; Dana, A.; Aydinli, A.; Rossetti, M.; Li L.; Dagli, N.; Fiore, A. (Optical Society of America, 2007)
      The electro-optic coefficients of self-organized InAs quantum dot layers in molecular beam epitaxy grown laser structures in reverse bias have been investigated. Enhanced electrooptic coefficients compared to bulk GaAs ...
    • Microcavity effects in the photoluminescence of hydrogenated amorphous silicon nitride 

      Serpengüzel, A.; Aydinli, A.; Bek, A. (1998)
      Fabry-Perot microcavities are used for the alteration of photoluminescence in hydrogenated amorphous silicon nitride grown with and without ammonia. The photoluminescence is red-near-infrared for the samples grown without ...
    • Phase-matched self-doubling optical parametric oscillator 

      Kartaloğlu, T.; Köprülü, K. G.; Aytür, O. (IEEE, Piscataway, NJ, United States, 1996)
      A new self-doubling optical parametric oscillator (OPO) uses a single nonlinear crystal for both parametric generation and frequency doubling. It is based on a KTiOPO4 (KTP) crystal pumped by a Ti:Sapphire laser operating ...
