Abstract

The goalis to develop and implement a control system for ring resonator-based Optical Beam Forming Networks (OBFNs). Beam shaping and beam steering, together called beamforming, is needed when processing radio-frequency signals from phased array antennas. This can be achieved in the optical domain, by tuning an OBFN. The tuning of such a network is the task of a control system. That system is the topic of research in this assignment. It enables thermo-optical tuning of ring resonator based OBFNs. In this thesis, the context, design and implementation of the control system are studied. Measurements are described to show the correct working of the implemented prototype. The control system may be used in the future in an airborne application. It may form part of a system that provides services such as radio, television, and internet access to en route aircraft. It is a challenge to make this possible. The control system consists of a controller and an interface to operate it. The controller has hardware and software aspects. The hardware is a modular set of components that can easily be extended when necessary. The software in the controller operates the hardware and provides the means for tuning OBFNs. A graphical interface is provided on a PC to operate the controller. This can easily be adapted to future needs. Two prototypes for the control system have been delivered in this assignment. The first prototype met the most important requirements but was not very easy to operate. The second implemented also met the more advanced requirements, enabled tuning of larger OBFNs, and was provided with an easy-to-use Java interface. The system has been used extensively in the TE lab and also at the Dutch Aerospace Laboratory (NLR). In the future, the system can be extended to provide angle and azimuth steering (to steer the beam to a certain point) and tracking and tracing functionalities (to find and keep focussed on a source).
