Radio-over-fiber has received renewed impetus due to various worldwide research initiatives in 5G. Here we will highlight recent developments at the device and integration level that are driving development of systems at various mmwave and sub-THz carriers, such as 30 GHz, 60 GHz and 120 GHz. Various device and circuit technologies will be reviewed in the framework of recent European projects. In addition, we will examine the outlook for monolithic and hybrid integration as a means of meeting size and power consumption requirements in picocell and femtocell applications.
