Abstract
We propose and experimentally demonstrate single-sideband (SSB) photonic vector millimeter-wave (mm-wave) signal generation enabled by optical dual-SSB modulation and a single push-pull Mach-Zehnder modulator (MZM). We use software-based digital signal processing to generate the dual-SSB driving signal for the push-pull MZM. The dual-SSB driving signal has a vector-modulated sideband and an unmodulated sideband, which are spaced by our desired mm-wave carrier frequency. After linear modulation of the push-pull MZM, optical filtering, and single-ended photodiode detection, we can get an electrical mm-wave signal displaying the same vector modulation as the aforementioned vector-modulated sideband. Based on our proposed scheme, we experimentally demonstrate the generation and transmission of a 40GHz mm-wave signal carrying 1Gbaud 16-ary quadrature-amplitude-modulation or 4Gbaud quadrature-phase-shift-keying transmitter data over a 10km single-mode fiber-28 and 0.5m air-space link, with a bit-error-ratio less than the hard-decision forward-error-correction threshold.
