SiPhotonics/GaAs 28-GHz Transceiver With Reflective EAM for Laser-Less mmWave-Over-Fiber

Exploring mmWave frequencies and adopting small-cell architectures are two key enablers for increased wireless data rates. To make these evolutions economically viable, centralized based on radio-over-fiber (RoF) devised. reduce the complexity of cellular network even further, RF-over-Fiber transmission schemes adopted in combination with reflective uplink operation. This paper relies a very low narrowband GaAs electronics / Si photonics transceiver scalable RFoF which we demonstrate fiber-wireless link capable transmitting over 7 Gb/s down- 2 km fiber 5 m 28 GHz band. Furthermore, it is shown that Rayleigh degradation caused by operation can be avoided using coherent detection scheme.
