Ultra-low Phase Noise Photonic-generated Millimeter Wave to Overcome the Capacity Limitation in Electronic D-band (110-170 GHz) Signal Generation

We lock ultra-low-noise lasers to generate a $153-\mathrm{GHz}$ millimeter-wave carrier with a record-low integrated ($10 \mathrm{~Hz}-10 \mathrm{MHz}$) jitter of 14 fs, outperforming a conventional electronic multiplier-based signal generator, resulting in $\gt 6 \mathrm{~dB}$ sensitivity enhancement using 10GBaud 64QAM.
