Novel Microwave Photonic Techniques in the Future Military Systems

Abstract

This paper reviews a number of novel applications of microwave photonic techniques in future military systems. One category is light interactions with microwave devices and circuits, which has contributed to the beginning of microwave photonics. The performance of HBT is the most attractive over FET and HEMT devices, due to its I-V dependence on high bandwidth and optical sensitivity. Moreover, different techniques of optical ADC are reviewed and among them all-optical ADC has the greatest promise of achieving high bit resolution. Microwave spectroscopy of biological tissues provides opportunity to create tomographic images of brain and breast, which leads to low-cost and reliable health monitoring of military personnel. A higher spatial resolution is obtained when a higher modulating frequency is employed. Finally, a new microchip laser is developed to generate frequency agile sources at microwave photonics. Optical sources operating at a fixed temperature will correspond to a beat signal, where a low phase noise beat signal is produced.
