Paper Abstract

Photonic delay lines (PDLs) are a powerful and important technology for microwave photonics applications and in particular for the implementation of wideband phased array antenna controllers since they solve many of the limitations of electronic controllers, such as large instantaneous bandwidth and tunable signal processing bandwidth. They also offer immunity to electromagnetic interference and electromagnetic pulses. Two of the most critical properties of PDL for advanced phased array antenna control are the fast switching speed and the accurate control of the time delays. In this paper, we propose a novel combined use of semiconductor optical amplifier (SOA) and OptiflexTM fiber circuit technology for the implementation of PDL architectures. Both technologies are currently quite mature and advanced. SOA technology has been used extensively on optical networks. On the other hand, Optiflex technology has been invented and used for optical backplanes and interconnects. In these PDL architectures, the SOAs act both as ultra-fast switching optical elements and as insertion loss compensators. On the other hand, accurate control of the time delays is achieved through the proper design of OptiFlex circuits. The integration of SOA and OptiFlex to build novel photonic delay line architectures provides small size, low power consumption, and ease in assembly, offering at the same time very good RF performance.
