Future System-on-Chip for Full Spectrum Utilization from RF to Optics
Event Details
The ever-increasing bandwidth requirement due to explosively growing 5/6G and AIoT data flows has compelled global commission authorities to release EM-spectra up to millimeter-wave (30-300GHz) and even (sub)-millimeter-wave frequency regimes (>300GHz) for massively expanded sensing and network applications. In this talk, we will exemplify novel CMOS-embedded technologies and methodologies developed at UCLA to enable System-on-Chip (SoC) realizations for multi-broadband radio, wideband radar, contactless/plastic interconnect, 3D-imaging and gas-phase rotational spectrometry at (sub)-mm-Wave frequencies.
We will also address challenges encountered in both design and implementations that may hinder further development of such systems, especially the major shortcomings in silicon technologies with limited dynamic range and power handling capabilities. We therefore propose replacing CMOS n-FET’s drain with selectively grown wide bandgap cubic-phase GaN (c-GaN) for >10X improved breakdown voltages to secure desired sensing/communication range/coverage with cost-effectiveness.
Additionally, we will elaborate on the possible growth of multi-wavelength light-emitting sources and detectors directly atop n-FinFET’s c-GaN Drain with various indium contents of InGaN/GaN super-lattice for RF-optical combined radio/radar/interconnect applications by creating unprecedented “Photonic System-on-Chip” with full EM-spectrum utilization from RF to optics.
