Flexible Multiband Signal Transmission using a Directly Modulated Laser over Photonically Generated 40 GHz

Popis výsledku v původním jazyce

Flexible multiband signal transmission is proposed and demonstrated over photonically generated millimeter wave signal at 40 GHz. The proposed scheme is based on a low cost directly modulated laser (DML) for data transmission and Mach-Zehnder modulator (MZM) for carrier suppressed double sideband modulation as the optical frequency multiplication scheme employed for millimeter wave signal generation. Multiple bands transmission with 50 MHz 16-quadrature amplitude modulation (QAM) have been experimentally demonstrated along 10 km standard single mode fiber (SSMF) link with a total bitrate of 1.2 Gb/s under a minimum RoP of -1.1 dBm. Further experiments with each band employing different modulation formats and bandwidths show successful performance up to 200 Mb/s using quadrature phase shift keying (QPSK), 16-QAM, 64-QAM bands, as a proof of concept towards flexible deployment of future networks, i.e. employing centralized radio access network (C-RAN) architecture.
