“…Unfortunately, the phase-noise performance is degraded when they are used for the millimeter-wave signal range. The centralized oscillator's signal distribution was reported in the literature from several sources [89][90][91][92]. For example, in [93], we proposed the use of an OEO as a LO in a 5G RAN fronthaul.…”

High-frequency signal oscillators are devices needed for a variety of scientific disciplines. One of their fundamental requirements is low phase noise in the micro- and millimeter wave ranges. The opto-electronic oscillator (OEO) is a good candidate for this, as it is capable of generating a signal with very low phase noise in the micro- and millimeter wave ranges. The OEO consists of an optical resonator with electrical feedback components. The optical components form a delay line, which has the advantage that the phase noise is independent of the oscillator’s frequency. Furthermore, by using a long delay line, the phase noise characteristics of the oscillator are improved. This makes it possible to widen the range of possible OEO applications. In this paper we have reviewed the state of the art for OEOs and micro- and millimeter wave signal generation as well as new developments for OEOs and the use of OEOs in a variety of applications. In addition, a possible implementation of a centralized OEO signal distribution as a local oscillator for a 5G radio access network (RAN) is demonstrated.

“…Our approach utlizes a low frequency reference signal [5] and the millimeter-wave carrier is generated by phase locldng technique [6] at the radio base station. This method is not affected by the dispersion problem (because the usual distances between the centre and the radio base stations are less than 10 km), relatively simple and utilizes inexpensive optical devices.…”

A novel optical cellular millimeter wave radio system is presented. The well-known methods in which the millimeter wave signal is distributed via a fiber have many drawbacks because they need very high speed photonic components. These problems are overcome by the new approach which utilizes a low frequency reference signal to phase lock a millimeter wave oscillator. The advantage of the new approach is in the application of low cost photonic components and in the small sensitivity to the fiber dispersion.
