Design and Simulation of an In Line Fiber Plasmonic Polarizer Payman Rasekh p rasekh@ec iut ac ir 2014 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree Master of Science Language Persian Farsi Reza Safian Dr Supervisor rsafian@cc iut ac ir Abstract Although photonic integrated circuits are fast comparing to the conventional electronic circuits one of the main concerns in this area is shrinking their size Plasmonics has helped shrinking photonic circuits mainly by sub wavelength confinement of light within the circuits Doing this plasmonic waveguides which are considered as transmission lines are increasingly focused These waveguides are in different types but the bear bone functionality of them is almost the same They are all based on the excitation of the Surface Plasmon Polariton SPP waves in the interface of metal and dielectric materials From another point of view in fiber based optical communication systems the performance and functional characteristics of many systems are based on the polarization of light passing through the fiber Therefore polarization management is necessary in the fiber communication systems optical gyroscopes and interferometer systems so as to prevent signal fading and error In order to get exact results dealing with only one polarization light is necessary Also enjoying high extinction ratio Fiber Based Polarizers for analysis and filtering is beneficial In this thesis a new hybrid plasmonic waveguide compatible with CMOS technology with propagation length in the order of about 40 mm is proposed This waveguide is fully analyzed and simulated Also a polarizer capable of distinguishing TE and TM modes is proposed based on the efficient waveguide The excitation ratio of the waveguide is about 33 dB Finally the structures are simulated and the results are discussed The simulations in this thesis are done by COMSOL Multi Physics software Keywords Surface Plasmon Polaritons Fiber based Polarizers Plasmonic Waveguides
