| The Faraday Effect has applications in Magneto-Optic Current transformers (MOCTs), Optical fiber current sensors, and highly sensitive current detectors. Faraday rotation angles and corresponding Verdet constant is known for SF-57, BK-7, and borosilicate type specialty glasses. An experimental system was built and validated for AC measurement of Verdet constant. Magneto-optic effect in a phosphate glass having Fe2O3 quantum dots was reported for the first time in this thesis.;Doping the glass with quantum dots increases the electron confinement energies upon excitement and magnifies the phase difference between the right and left circularly polarized light thus enhancing the Faraday rotation angle and hence the Verdet constant for that material, which is dependent on wavelength and temperature, resulting in high magneto-optic effect.;The measured Verdet constant values were 11.65, 2.54, and 0.0692 °/T-cm for SF-57, BK-7, and borosilicate rods, respectively, and conform to the literature. The quantum dot doped phosphate glass gave Verdet constant of 5.17 °/T-cm for 1% doping concentration which was approximately 17 times more than the Verdet constant of the plain phosphate glass. |
