An optoelectronic multiplexer for wireless transmissions of high‐speed data‐modulated microwave sub‐carriers

In this article, an optoelectronic multiplexing scheme is reported. This scheme results from the association of a multimode laser and the chromatic dispersion on standard single mode optical fiber. The frequency response of this system shows a series of microwave band-pass windows, which can be used for allocating modulated microwave subcarriers. Under this operating principle, the multiplexing of two data-modulated microwave subcarriers at 2.4 and 7.2 GHz is described in this work. 100 Mbps-NRZ and vector digital data (QPSK, mQAM) were transmitted and evaluated. The performance of the multiplexing scheme shows that it can be used for high-speed wired or wireless transmissions. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:486–490, 2016
