Abstract

We present a photonic-assisted arbitrary waveform generation for uplink applications in beyond 5G taking advantage of low frequency technology and it has a potential to upgrade signal frequency from MHz to more than tens GHz retaining the high ENOB of conventional low frequency electrical technology competitive to the state of the arts of tens GHz class AWG. In machine-to-machine communications over uplink traffic as one of application scenario examples, massive multi-data should be accommodated and be conveyed to beyond GHz region in the era of beyond 5G. The proposed photonic assistance for temporal waveform compression has a potential to upgrade signal frequency from MHz to more than tens GHz retaining the high ENOB of the low frequency technology and surpass the state of the arts of tens GHz class AWG. We successfully demonstrate the principle of the proposed approach in experiment and the potential of achievable ENOB over 12 bit at 50 GHz in simulation.
