Interferometric interrogation concepts for integrated electro-optical sensor systems

Integrated optical sensors have a high potential in the measurement of a large variety of measurands. Research on integrated optical sensors enjoys increasing interest. In order to reach accurate performance and to facilitate the use of integrated optical sensors, electronic functions for sensor interrogation are required. This thesis presents several coherent interferometric interrogation concepts (system architectures) for phase modulating integrated optical sensors. It also focuses on the determination of both quasi-static and dynamic components of the measurand. On-chip electronic circuitry may eventually lead to a smart sensor.
