Abstract
We demonstrate CMOS-integrated mm-wave-to-optical sensing elements comprising LNAs and triple-ring modulators that break the conversion-bandwidth tradeoff, showing a projected noise figure of 24 dB at 57 GHz (30 mW/element, -45dBm RF-input, 6dBm laser LO). The elements are tileable at small pitches, enabling photonic disaggregation of large-scale phased arrays.
