  • RF-CMOS Electronic-Photonic Sensing Elements for Millimeter-wave Front-end Systems-on-Chip: Enabling mm-wave Array Scaling/Disaggregation for Radar and Extreme Massive MIMO
Title: RF-CMOS Electronic-Photonic Sensing Elements for Millimeter-wave Front-end Systems-on-Chip: Enabling mm-wave Array Scaling/Disaggregation for Radar and Extreme Massive MIMO
We demonstrate a path to scalable, wavelength- multiplexed RF/mm-wave-photonic front-end systems-on-chip for radar and extreme massive MIMO arrays, in 300mm-foundry 45nm RF SOI CMOS. We demonstrate mm-wave-to-optical sensing elements comprising low-noise amplifiers (LNAs) mono- lithically integrated with triply-resonant photonic microring- resonator based modulators. The “photonic molecule” modulator concept breaks the conventional ring modulator conversion efficiency-bandwidth tradeoff and provides optimal performance RF-photonic applications, while supporting high bandwidth den- sities. We show a first experiment with projected noise figure of 24dB at 57GHz (30mW/element, -45dBm RF-input, 6dBm laser LO). The elements are tileable at small pitches, enabling photonic disaggregation of large-scale phased arrays.  more » « less

    We show efficient wide-tunable mm-wave-to-optical transduction (20 to 70 GHz at -9 to -18 dBc) using a triple-microring modulator. Integrated monolithically with a 18% bandwidth LNA, it generates sidebands with <−35 dBm RF input.

    A RF photonic front-end using dual-differential driving scheme is reported with a 22nm CMOS FD-SOI driver co-integrated with a silicon traveling-wave Mach-Zehnder modulator. The proposed front-end achieves 15-25GHz bandwidth with 2dBm IIP3 and consumes 448mW.

    Radio-frequency (RF) waveform synthesis has broad applications in ultrawide-bandwidth wireless communications, radar systems, and electronic testing. Photonic-based approaches offer key advantages in bandwidth and phase noise thanks to the ultrahigh optical carrier frequency. In this work, we demonstrate Fourier synthesis arbitrary waveform generation (AWG) with integrated optical microresonator solitons. The RF temporal waveform is synthesized through line-by-line amplitude and phase shaping of an optical soliton microcomb, which is down-converted to the RF domain through dual-comb optical coherent sampling. A variety of RF waveforms with tunable repetition cycles are shown in our demonstration. Our approach provides not only the possibility of precise Fourier synthesis at microwave and millimeter-wave frequencies, but also a viable path to fully integrated photonic-based RF AWG on a chip.

    An RF photonic front-end using dual-differential driving scheme is reported with a 22nm CMOS FD-SOI driver co-integrated with a silicon traveling-wave Mach-Zehnder modulator. A compact design of power splitter and output routing network are implemented on dual-differential driver. An LC input matching network co-designed with bond wire inductance is implemented on a photonic chip to complete the output matching network. The proposed driver is verified with S-parameter and two-tone measurements, achieving 15-25GHz bandwidth with peak 3dBm IIP3 and consumes 448mW. The link performance is demonstrated 12.1% EVM of 16-QAM modulation with 2Gbd at 20GHz carrier frequency.

    We demonstrate a coupled-cavity electro-optic modulator with 5.5 GHz bandwidth centered at 41 GHz. The device, driven with a −5 dBm RF signal, shows −27 dB pump-to-sideband conversion efficiency, a 15 dB improvement over a regular ring modulator.
