    With a transparency window up to 6 μm, sapphire can serve as a platform to support silicon photonic integrated circuit in MWIR. Planar waveguide devices based on silicon-on-sapphire (SOS) are emerging as a bridge between ...
  • Ginsburg, Brian P.,; Nagaraj, Krishnasawamy; Nayak, Neeraj; Özgün, Mehmet Tamer; Subburaj, Karthik; Murali, Sriram; Ledesma, Francisco (IEEE, 2011-06)
    An FM frequency synthesizer and antenna driver with >;63dB SNR, <;0.1% THD, and -101dBc out-of band emissions at 124 dBμV output swing in 65 nm digital CMOS is described. The optimized FLL incorporates a DCO with a highly ...
  • Boyraz, Özdal; Huang, Yuewang; Sang, Xinzhu (Society of Photo-optical Instrumentation Engineers, 2012)
    Conventional SOI waveguide technology, serving as the foundation of near-IR photonics, meets its limitation in mid-IR due to high loss associated with the buried oxide. Silicon-on-sapphire (SOS) waveguides are considered ...
  • Arıcı, Tarık; Aksakallı, Vural (SciTePress, 2012)
    Energy minimization algorithms are used in low-level computer vision applications for labeling tasks such as stereo-disparity estimation, image restoration, motion estimation, and optical flow. The energy function involves ...
  • Kalyoncu, Salih K.; Song, Qi; Huang, Yuewang; Boyraz, Özdal (IEEE, 2012-09)
    We demonstrate fast optical arbitrary waveform generation by using MEMS digital micro-mirror arrays. Experimentally, we obtain ~120MHz waveforms that can be controlled by using 1024×768 mirror arrays. 1GHz waveforms ...
  • Polat, Nafiye (IEEE Computer Society, 2013)
    Entity disambiguation is the task of identifying the real world entity was referred to in a context. Ambiguous references to entities can occur due to variations of how entity was referenced (BT, British Telecom) or inherit ...
  • Akhmedov, Murodzhon; Çatay, Bülent; Apaydın, Mehmet Serkan (IEEE, 2013)
    The key bottleneck of Nuclear Magnetic Resonance (NMR) studies is to map the NMR peaks to corresponding nuclei, also known as the assignment problem. Structure Based Assignment (SBA) is an approach to solve this computationally ...
