Abstract

We propose and demonstrate a microwave photonic communication system with tunable wireless multi-waveband based on pulse shaping, direct detection, and multi-wavelength optical comb. Duo to the parameter configuration and RF- photonics modulation, the number of the flat channels output from a multi-wavelength optical comb can be up to 21. In the near terminal unit of the communication system, four adjacent optical sources output from the multi-wavelength optical comb can be obtained. One of the four optical sources is modulated by a RF vector signal with the frequency of 5 GHz. A single sideband optical signal can be obtained from the modulated signal by pulse shaping via a Gaussian optical filter. The single sideband optical signal and the other three optical sources are coupled into a standard single-mode fiber with 50 km, and then reach the remote terminal unit of the communication system, in which the wireless carriers with the frequency of 5 GHz, 25 GHz, 45 GHz, and 65 GHz can be obtained via a photoelectric direct detector. These multi- carriers can be employed for wireless transmission between the mobile terminal and the remote terminal unit; in addition, three pure optical sources utilized for the uplink can be obtained in the meantime.
