Optical Phase Modulation Utilizing Magnetoelastic Properties Of Metallic Glasses, Frank R. Trowbridge
Optical Phase Modulation Utilizing Magnetoelastic Properties Of Metallic Glasses, Frank R. Trowbridge
Retrospective Theses and Dissertations
Three different optical fiber phase modulators utilizing the magnetostrictive properties of the metallic glass alloy Fe74Co10B16 were constructed. By binding the optical fiber to the magnetostrictive metallic glass, the strain imparted to the metallic glass from the magnetic field is transferred to the optical fiber. The strain on the optical fiber shifts the phase of the light, which can be controlled indirectly by varying the current producing the magnetic field permeating the metallic glass. The performance of the modulators on the basis of optical phase shift as a function of bias magnetic field and optical phase shift as a function …

A Ten Kilometer Transmission System Fiber Optics Versus Ku-Band, John A. Hallmark
Retrospective Theses and Dissertations
This research paper discusses the design evaluation and selection of a transmission system to be used in checking out the Spacelab high rate data system. The transmission systems evaluated are discussed, as well as the criteria utilized in selecting the final system. The installation of a fiber optics cable and the testing of this cable are discussed. The determination of the optimum location of the high rate data bit synchronizer and Viterbi decoder is presented. Utilization of this data to justify the installation of a shorter fiber optics system inside the O&C Building is presented.
