Reconfigurable radiofrequency (RF) signal generation in the 30–300 GHz range is attractive for many applications. W-band (75–110 GHz) is currently targeted by both wireless and satellite commun…
We report of a silicon photonics (SiP) flat-top bandpass microwave photonic (MWP) filter with large out-of-band power rejection (OBPR) of up to more than 40 dB and exhibiting central frequency tuna…
Soon after its introduction in the communications domain, the novel concept of multiple input–multiple output (MIMO) has been making its way also into the radar world. A new generation of multist…
Currently, due to the 6G revolution, applications ranging from communication to sensing are experiencing an increasing and urgent need of software-defined ultra-wideband (UWB) and tunable radio fre…
We propose a novel photonic-integrated single-sideband (SSB) modulator realized in silicon on insulator technology operating either in suppressed-carrier or full-carrier mode with continuously tuna…
We report on the characterization of a photonic integrated circuit (PIC) for the generation of a RF carrier in the millimeter-wave band up to the sub-THz region. The circuit is implemented in silic…
A two-layer switch exploiting orbital angular momentum (OAM) and wavelength of the light as switching domains is presented, aiming to increase the scalability with respect to the single-layer switc…
This work reports the first realization of a combined radar&lidar system based on silicon-on-insulator photonic integrated circuit (PIC). The software-defined architecture comprises a frequency-fle…
Thermally controlled silicon photonics microwave phase shifters suffer from slow reconfiguration time that practically limits their application fields. A microwave photonics phase shifter exploitin…
