LATEST ELECTRO-OPTIC AND PHOTONIC DEVICES FOR SECURITY AND MILITARY APPLICATIONS

摘要

This paper reveals performance capabilities of state-of-the-art electro-optic and photonic devices, which are best suited for security and defense system applications. These devices can be used in battlefield, space surveillance, medical diagnosis, and detection of terrorist activities. Performance capabilities of fiber optic components for possible applications in WDM and DWDM systems are summarized. Photonic devices for covert military and security communication applications are identified with particular emphasis on performance and reliability. Performance parameters of Erbium-doped fiber amplifiers (EDFAs), Erbium-doped waveguide amplifiers (EDWAs), and optical hybrid amplifiers (OHAs) comprising of EDFAs and Raman amplifiers are discussed with emphasis on bandwidth, gain-flatness, data handling capability, channel capacity and cost-effectiveness. Performance parameters of very long wavelength infrared (VLWIR) detectors are summarized, which have potential applications in remote sensing and ballistic missile defense applications. Electro-optic and photonic devices best suited for security and defense applications are identified.
