Paper Abstract

Operation of a microwave system involve generation, manipulation and most importantly, transportation of signals throughout the system. A well known example in which signal transportation plays a crucial role is a phased array radar system, in which hundreds or even thousands of individual emitting elements must be synchronized and appropriately phased for proper operation. Optical fiber is an excellent medium for transportation of high speed signals. Microwave signals can be imposed on an optical carrier by direct modulation of a laser diode[1]. Present state of the art high speed laser diodes have direct modulation bandwidths of beyond 20GHz, with the potential of reaching the 30GHz range by using quantum well laser structures[2]. At the present moment it does not seem probable to extend the direct modulation bandwidth to the millimeter wave range of approximately 100GHz using established approaches.
