Abstract

To support enhanced mobile broadband (eMBB) communication, 5G is going to use new radios (NRs) at frequencies above 24.25 GHz in the millimeter-wave (mm-wave) bands with abundant available bandwidths. The photonic generation, modulation and distribution of such ultra-high speed broadband RF signals in the optical domain is more promising compared to the bandwidth limiting electrical technology, however, it requires low noise coherent optical sources. In this paper, we present a highly coherent low noise InP-based p-n block buried heterostructure (BH) C-band InAs/InP quantum dash (QD) passively mode-locked laser (MLL) for photonic aided broadband wireless communication systems. The device features repetition rates of 25 GHz resulting in an optical coherent frequency comb (CFC) with a 6-dB optical bandwidth of around 9 nm providing over 46 channels. Each individual channel of the CFC exhibits an average phase noise and integrated relative intensity noise (RIN) of less than 500 kHz and -130 dB/Hz in the frequency range from 10 MHz to 20 GHz, respectively. Its timing jitter and RF beat-note linewidth between any two adjacent channels are as low as 5.53 fs and 3 kHz, respectively. By using this QD MLL, a photonic aided radio-over-fiber (RoF) broadband quadrature amplitude modulated (QAM) signal wireless delivery at around 25 GHz (K-band) is successfully demonstrated over 2-m free space wireless distance through 25.22 km standard single-mode fiber (SSMF) with a total link capacity of 16Gbit/s and error vector magnitude (EVM) below the standard requirements of 12.5%.
