Radar and electronic warfare applications of multigigahertz optical components and systems
Recent advances in wideband components for use in optical fiber systems have been very impressive. Laser diodes have shown 3 dB modulation band-widths near 20 GHz at room temperature and external modulators with similar high-frequency performance have been reported. Bandwidths as high as 100 GHz have been achieved in semiconductor photodiodes. Performance of these components at such high frequencies opens a new realm of possibilities for the use of optics in military systems.
