We present computational design and investigation of nano-optical systems involving nanowires and well-designed nano-couplers to effectively transmit electromagnetic power in nanometer scales. Different nano-couplers, which consist of optimal arrangements of nano-cubes, are carefully designed by considering various scenarios, e.g., nanowire lines with sharp corners and junctions. An efficient combination of genetic algorithms and the multilevel fast multipole algorithm is used to find suitable configurations of nano-cubes that provide desired electromagnetic responses. Combinations of multiple nano-couplers and nanowires allow us to build larger nano-optical systems with different shapes, inputs, and outputs. Initial results presented in this paper demonstrate the feasibility of complex networks based on nanowires and nano-couplers.

Design and Analysis of Nanoantenna Arrays for Imaging and Sensing Applications at Optical Frequencies Isiklar, Goktug; Cetin, Isa Can; Algun, Mustafa; Ergül, Özgür Salih (2019-01-01) We present computational analysis of nanoantenna arrays for imaging and sensing applications at optical frequencies. Arrays of metallic nanoantennas are considered in an accurate simulation environment based on surface integral equations and the multilevel fast multipole algorithm developed for plasmonic structures. Near-zone responses of the designed arrays to nearby nanoparticles are investigated in detail to demonstrate the feasibility of detection. We show that both metallic and dielectric nanoparticles...
Design of Compact Nano-Optical Couplers Involving Dielectric Nanorods Karaosmanoglu, Bariscan; Yazar, Sirin; Ergül, Özgür Salih (2018-06-01) We present optimization and design of nano-optical couplers involving dielectric nanorods. Using tens of elements, optimal array configurations are found to produce alternative responses that can be digitized. For realistic simulations, the couplers are modeled as three-dimensional structures and analyzed via surface integral equations and the multilevel fast multipole algorithm (MLFMA). Initial results are presented demonstrate the feasibility of compact but effective couplers with desired responses.
Investigation of Alternative Array Configurations of Nanowires for Maximum Power Transmission at Optical Frequencies Karaosmanoglu, Bariscan; Satana, Hasan Aykut; Dikmen, Fatih; Ergül, Özgür Salih (2017-07-14) We present a computational analysis and comparison of nanowire arrays for efficient transmission of electromagnetic power at optical frequencies. A reliable simulation environment involving the multilevel fast multipole algorithm for fast iterative solutions of surface integral equations is used to accurately compute field intensity and power density values in the vicinity of nanowires in diverse configurations. The results demonstrate favorable properties of honeycomb structures that can provide efficient ...
Design and analysis of ultrashort femtosecond laser amplifiers Doğan, Ersin; Bilikmen, Kadri Sinan; Department of Physics (2006) This thesis presents a compact femtosecond laser amplifier design for optical preamplifiers and power amplifiers consist of theoretical perspective, simulations to analyze and optimize beam performance. The propagation through optical media is simulated for every optical component such as mirrors and nonlinear crystal separately and suggested realignment of these components required increasing amplifier performance. Finally Gaussian beam propagation and aberration compensation has been conducted.
In-orbit estimation of time-varying residual magnetic moment for small satellite applications Söken, Halil Ersin (2013-09-16) A method for in-orbit estimation of time-varying residual magnetic moment is presented for small satellite applications. The Unscented Kalman Filter is used as the estimator. Unlike the existing studies in the literature, unexpected abrupt changes in the residual magnetic moment are also considered. Sudden shifts in the mean of the residual magnetic moment is detected by a low pass filter applied to the normalized innovation of the Unscented Kalman Filter. Then, by using a simple approach, which does not re...
