Conference Object Citation - WoS: 39Optical Layer Monitoring in Passive Optical Networks (pons): a Review(Institute of Electrical and Electronics Engineers Inc., 2008) Yüksel, Kıvılcım; Yüksel Aldoğan, Kıvılcım; Wuilpart, Marc; Mégret, Patrice; 03.05. Department of Electrical and Electronics Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyMotivations, challenges and requirements of optical layer monitoring in PONs are discussed. An exhaustive review of monitoring systems is given considering both Time-Division Multiplexed PON (TDM-PON) and Wavelength-Division Multiplexed PON (WDM-PON) cases. © 2008 IEEE.Conference Object Citation - WoS: 3Citation - Scopus: 3Spin Polarized and Degenerate Tunneling Spectra in Intrinsic Josephson Junctions of Bi2212(John Wiley and Sons Inc., 2007) Özdemir, Mustafa; Özyüzer, Lütfi; Özyüzer, Lütfi; 04.05. Department of Pyhsics; 04. Faculty of Science; 01. Izmir Institute of TechnologyTunneling characteristics of HgBr2 intercalated superconducting Bi2212 single crystals have been obtained by using 10×10 μm2 intrinsic Josephson junction stacks, so called mesa structures. The spin degenerate current is driven along the c-axis with Au layer using point contact tunneling assembly at 4,2 K. The spin polarized current is also driven along the c-axis of crystals with Au/Co/Au multilayer. In order to understand the role of ferromagnetic layer (Co), quasiparticle branches are examined with and without magnetic field. The magnetic field evolution of switching currents are obtained for gaining further insight about the spin injection through the stack
