TL;DR: The design and characterization of Si₃N₄/SiO₂ optical waveguides which are specifically developed for optical delay lines in microwave photonics (MWP) signal processing applications and the potential of the waveguide technology to be applied to construct compact on-chip MWP signal processors are reported.

TL;DR: An integrated photonic signal processor consisting of a reconfigurable optical delay line (ODL) with a separate carrier tuning (SCT) unit and an optical sideband filter on a single CMOS compatible photonic chip is reported.

TL;DR: In this paper, a ring resonator-based 1-times-8 optical beam forming network (OBFN) was proposed for phased array antenna systems, where a binary tree topology is used for the network such that a different number of ORRs is cascaded for delay generation at each output.

TL;DR: A novel, hardware-compressive architecture for broadband and continuously tunable integrated optical true-time-delay beamformers for phased array antennas is proposed and experimentally demonstrated, and the first demonstration of an integrated beamformer where the periodic response of ORRs is exploited to process signals from different antenna elements, simultaneously, using a single delay line is demonstrated.

TL;DR: This is the first-time on-chip demonstration where ring resonators are employed to perform phase control functionalities for optical generation of microwave signals by means of optical heterodyning.
