Description
Modern phased array sensors demand wideband operation and large instantaneous bandwidths, without suffering from beam-squint. True time delay (TTD) allows for multi-octave squint-free operation; however this becomes impractical to implement in electronics for large arrays, requiring extreme angles of beamsteering for multiple simultaneous beams, especially on small platforms like unmanned aircraft systems (UAS). Freedom Photonics proposes to develop a low cost, size, weight and power (C-SWaP) photonic integrated time delay unit (TDU) for simultaneous RF multi-beamforming, by utilizing expertise in photonic integration, and leveraging the combined benefits of active-devices in photonic integrated circuits (PICs).
