All‐optical RF amplification toward Gpbs communications and millimeter‐waves applications

We propose and experimentally investigate the use of an ultra‐wideband photonics‐assisted RF amplifier for Gbps communications and mm‐waves applications, including 5G cellular networks. A 2 Gsymb/s broadband signal with different modulation formats has been used for evaluating the all‐optical RF amplifier, as a function of diverse electrical and optical figures of merit, including RF gain, signal‐to‐noise ratio, linearity, constellation, and error vector magnitude.
