Operational application of Microwave Photonics
the Analog Photonic Link and the Spurious Free Dynamic Range
Abstract
The The first devices to deploy Microwave Photonics technologies date from the nineties. Since then, several improvements have been made in radiofrequency (RF) systems which use photonic devices, deployed along or replacing electronic devices. Photonic devices have been used in Analog Photonic Links (APL) seeking commercial civilian applications or applications that are interesting to the military. This way, one feature to be studied is the Spurious Free Dynamic Range (SFDR), which limits, for instance, sensibility and distortion-free operation of a radar or an electronic warfare system. This article also points at APLs advantages, since they provide higher efficiency to associated RF systems, once photonic devices are used there. It is foreseen that military systems deploying these devices will be commercially available in the near future, inside weapons systems and electronic warfare systems, given the requirements of battlefield scenarios and the evolutions predicted to microwave photonics technologies.
