Modulation formats for wavelength division multiplexing (WDM) systems
Büyükşahin Öncel, F. Feza; Çakır, Serhat; Department of Physics (2009)
Optical communication networks are becoming the backbone of both national and international telecommunication networks. With the progress of optical communication systems, and the constraints brought by WDM transmissions and increased bit rates, new ways to convert the binary data signal on the optical carrier have been proposed. There are different factors that should be considered for the right choice of modulation format, such as information spectral density (ISD), power margin, and tolerance against gro...
Dynamics of extended objects in general relativity
İlhan, İbrahim Burak; Tekin, Bayram; Department of Physics (2009)
In this thesis, multipole expansions of mass, momentum and stress density will be made for a body in Newtonian mechanics. Using these definitions; momentum, angular momentum, center of mass, force and torque are defined for N gravitationally interacting isolated bodies. Equations of motions of such a system are derived. Definitions of momentum, angular momentum, center of mass, force and torque are made in a relativistic theory. Dynamical (gravitational) skeleton is defined and the multipole moments of the ...
Radiative B-*->B gamma and D-*->D gamma decays in light-cone QCD sum rules
Alıyev, Tahmasıb; Iltan, E; Pak, NK (1996-07-01)
The radiative decays B*(D*)-->B(D)gamma are investigated in the framework of light-cone QCD sum rules. The transition amplitude and decay rates are estimated. It is shown that our results for the branching ratios of D meson decays are in good agreement with the existing experimental data.
Optical design and analysis of a riflescope system
Bayar, Cevdet; Esendemir, Akif; Department of Physics (2009)
Today, riflescope systems are used widely, mostly by military forces. In this study, a riflescope working in the visible range (400-700 nm) will be designed. The riflescope will have 3 degrees field of view and maximum 15 cm total track. Total design length is limited to 15 cm because a short riflescope is more stabilized than a long one with respect to thermal instability and vibrational effects. Taken into account the cost factor, only two types of glasses will be used in the design. One of them is NBK7 a...
Design of reflective and antireflective coatings for space applications
Eroğlu, Hüseyin Cüneyt; Esendemir, Akif; Department of Physics (2009)
In order to improve the efficiency of various optical surfaces, optical coatings are used. Optical coating is a process of depositing a thin layer of a material on an optical component such as mirror or lens to change reflectance or transmittance. There are two main types of coatings namely; reflective and antireflective (AR) Coatings. Reflective and antireflective coatings have long been developed for a variety of applications in all aspects of use; for optical and electro-optical systems in telecommunicat...
