Abstract

The Kramers-Kronig (KK) receiver, applicable in fiber-optic communications, can reconstructs a complex-valued signal from detection of its intensity, and thereby greatly reduce the receiver complexity to a single photodiode. Here, a single-laser photonic-wireless millimeter-wave communication system based on the KK scheme is proposed. We use the high-order sideband modulation of the Mach-Zehnder modulator (MZM) to obtain the two difference frequency components f1 and f2 required by the KK scheme with only a single laser. In addition, combined with virtual carrier technology, only one laser is required at the transmitter. The proposed single-laser scheme significantly simplifies the transmitter compared with the traditional dual-laser and three-laser schemes. For proof of concept, we demonstrate a 120 GHz photonic-wireless link using QPSK and 16QAM modulation, which can achieve 60 Gb/s QPSK and 120 Gb/s 16QAM transmission in the simulation environment.
