Analysis of the generation of amplitude-squeezed light with Gaussian-beam degenerate optical parametric amplifiers
(OSA Publishing, 2001-06)We investigate the generation of amplitude-squeezed states with degenerate optical parametric amplifiers that are pumped by focused Gaussian beams. We present a model that facilitates the calculation of the squeezing level ... -
Broadband GaN LNA MMIC development with the micro/nano process development by kink-effect in S22 consideration
(Bilkent University, 2021-01)Broadband low noise amplifiers (LNA) are one of the key components of the nu-merous applications such as communication, electronic warfare, and radar. The requirements for higher bandwidth, higher speed, higher survivability, ... -
High-power-high-repetition-rate-single-mode Er-Yb-doped fiber laser system
(Optical Society of America, 2012)We demonstrate an all-fiber-integrated, high-power chirped-pulse-amplification system operating at 1550 nm. The seed source is a soliton fiber laser with 156 MHz repetition rate. Two-stage single mode amplifier provides ... -
Junction characteristics and magnetic field dependencies of low noise step edge junction Rf-SQUIDs for unshielded applications
(IEEE, 2003-06)Step edge grain boundary (GB) junctions and rf-SQUIDs have been made using pulsed laser deposited Y-Ba-Cu-O films on crystalline LaAlO3 substrates. The steps were developed using various ion-beam etching processes resulting ... -

Noise problem in primary schools in Ankara
(Bilkent University, 1994)In this study, the problem of noise in primary schools is examined, by indicating the negative effects of this problem on the physiological, psychological, and social well-being of human beings, and on the effectiveness ... -
Noise, junction characteristics, and magnetic field dependencies of bicrystal grain boundary junction Rf-SQUIDs
(IEEE, 2003)Bicrystal grain boundary (GB) Josephson junctions and rf-SQUID's were made of 200 nm thick PLD YBCO films on bi-crystal SrTiO3 substrates. The junction characteristics were studied to investigate optimal parameters in the ... -
Numerical analysis of multidomain systems: coupled nonlinear PDEs and DAEs with noise
(Institute of Electrical and Electronics Engineers, 2018)We present a numerical modeling and simulation paradigm for multidomain, multiphysics systems with components modeled both in a lumped and distributed manner. The lumped components are modeled with a system of differenti ... -
Online learning under adverse settings
(Bilkent University, 2015-05)We present novel solutions for contemporary real life applications that generate data at unforeseen rates in unpredictable forms including non-stationarity, corruptions, missing/mixed attributes and high dimensionality. ... -
Optimal channel switching for average capacity maximization
(IEEE, 2014-05)Optimal channel switching is proposed for average capacity maximization in the presence of average and peak power constraints. A necessary and sufficient condition is derived in order to determine when the proposed optimal ... -
Parametric power spectral density analysis of noise from instrumentation in MALDI TOF mass spectrometry
(2007)Noise in mass spectrometry can interfere with identification of the biochemical substances in the sample. For example, the electric motors and circuits inside the mass spectrometer or in nearby equipment generate random ... -
Role of the environmental spectrum in the decoherence and dephasing of multilevel quantum systems
(The American Physical Society, 2005)We examine the effect of multilevels on decoherence and dephasing properties of a quantum system consisting of a nonideal two level subspace, identified as the qubit, and a finite set of higher energy levels above this ...
