Photonic signal processing of microwave signals

Integrable microwave filter based on a photonic crystal delay line

“…MWP signal processors reported so far [12][13][14][15][16] have relied on discrete optoelectronic devices and standard optical fibre delay lines, and components leading to bulky, expensive and powerconsuming architectures. Typical delay line footprints range from several tens of centimetres when using fibre Bragg gratings (FBGs) to a few kilometres when using standard optical fibres.…”

Tunable Photonic Microwave Filters Based on Opto-VLSI Processors

“…P HOTONICS-BASED processing of microwave and millimeter-wave signals is a powerful technique that offers advantages such as ultrawide bandwidth, immunity to electromagnetic interference, flexibility, and lightweight [1]- [3].…”

Widely Tunable Microwave Photonic Notch Filter Based on Slow and Fast Light Effects

“…ICROWAVE photonics has already attracted considerable interest for processing microwave or millimeter-wave signals directly in the optical domain [1]- [3], due to its huge bandwidth, inherent speed, immunity to electromagnetic interference, and low loss. One important application of interest is the microwave photonic notch filter, which has potential for broadband wireless access networks and radar systems.…”
