“…The up-conversion of a MW signal to an optical carrier allows photonic signal processing techniques with a drastic SWaP-C reduction over the entire bandwidth. Photonic devices have recently been proposed and applied to innovative MW photonic spectrometer architectures [2,3]. In this scenario, photonic integrated circuits (PIC) are characterized by several benefits, such as the reduction in system footprint, low power consumption, broad operation bandwidth, and immune to radio frequency interference [4].…”
