Integrated optics for instrumentation applications: Dissertation

    Research output: ThesisDissertationCollection of Articles


    An asymmetric bus access coupler for a passive linear bidirectional fiber optic bus and a combined optical-to-electrical power converter and bidirectional optical data transceiver were demonstrated. These customized multimode integrated optics devices were made using electric field assisted Ag-Na ion-exchange processes. A single-mode diode-laser-to-waveguide butt-coupling model, which can be used for coupling efficiency and alignment tolerance analysis, was developed. The feasibility of multimode fiber pigtailing using an active alignment technique with a sleeve construction and a passive alignment technique with a grooved substrate was shown.
