Slab coupled optical fiber sensors for electric field sensing applications

摘要: Slab Coupled Optical Fiber Sensors for Electric Field Sensing Applications Richard Scott Gibson Department of Electrical and Computer Engineering Doctor Philosophy This dissertation presents the creation slab coupled optical sensors (SCOS) electric field sensing applications. SCOS devices utilize benefits an fiber system high bandwidth low electromagnetic interference. These are fabricated by means mode coupling between a small section D-shaped (D-fiber) with multi-mode electrooptic waveguide. detection is accomplished monitoring behavior resonances, seen as transmission dips in D-fiber transmission, they shift fields. The novelties include their compact nature, potential sensor multiplexing dielectric structure allowing developed this work been used to measure fields 30 V/m 1 kHz resolution degree linearity. Due size capable placement within interior immeasurable other that either too large internal or disruptive due metallic structure. Wavelength allows multiple be placed on single mapping at instances. As extension, 3-d use electro-optic crystals having orthogonal orientations axis. performs thorough analysis design order optimize efficiency its various Furthermore, straightforward fabrication process these outlined development future uses sensors.
