Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE credits
Today the nanotechnology and micro-fabrication of devices have effect in all technology researches and industry fields as in photonics. Using of light or laser light is almost important in the field of physic, medical, biology and chemistry as well as for related application.
Development and investigation in photonics allows better use of much more detailed knowledge like as quantum effects at the single photon level or as non-classical light. Light with orbital momentum, noise and different idea about coherent properties and etc. leads to new experiments and applications. Such new devices are microstructure fiber, new laser or new nonlinear materials and superconductor. However photonic is very width and this paper covers some basic details about integrated photonics and the basic principles for characterization of dielectric material in integrated photonics .
This thesis consists of several chapters and the aim of the thesis is characterization of optical properties on novel oxide films for integrated photonics application. Chapter I includes different parts, which are presentation of the photonic scientific background in details, as well as the key points of the study and development. Chapter II describes some applications of integrated photonics waveguide.
Chapter III consists of description of the experimental method: Spectroscopic Ellipsometry, COMSOL and MATLAB, Which we used during this thesis. From Spectroscopic Ellipsometry experiment we get the data for transmittance spectra in certain wavelength then we used information from Ellipsometry to plot transmittance spectrum vs. wavelength and fit it in MATLAB to find refractive index for two different samples (NbOx and Bi3Fe5O12) and compared the experimental and simulation data. We find the complex refractive index (n-ik) for each material by fitting the plot in Matlab through using the Sellmeier-like formula. COMSOL is other software simulation we used to simulate the electric and magnetic filed for NbOx thin film as rib waveguide on corning glass substrate.
At last chapter IV consists of conclusion. This thesis will be compact information about light, waveguides and dielectric materials include formulas and parameters and some overview to related physics.
