The term microwave photonics refers to the generation, distribution and processing of analog radio-frequency, microwave and millimeter-wave signals over optical fibers and photonic devices. Microwave photonics takes up an increasing role in advanced cellular and wireless networks. Optical fibers extend the reach and coverage of such networks in areas where direct reception is impossible. Microwave photonics is also a significant part of many radar systems. Our group has been working in microwave photonics since its establishment. Areas of contributions include variable optical delay lines, tunable microwave filters, high-resolution spectral analysis, and generation of low-noise microwave and millimeter-wave tones.
