Plasmonic phased array feeder enabling symbol-by-symbol mm-wave beam steering at 60 GHz

We demonstrate an on-chip 60 GHz phased array antenna feeder with record-low footprint (active area <;2.5μm
²
), based on ultra-compact plasmonic modulators. The chip footprint is only limited by the contact pads size. Our implementation also enables ultra-fast steering with less than 1 ns reconfiguration time.
