Implementation of a photonics-based frequency reconfigurable optical-wireless network

This work reports the implementation of a frequency reconfigurable optical-wireless network based on a photonics technology. An optical modulator is used to dynamically manage and manipulate RF signals over different frequency bands by means of optical frequency multiplication. The proposed concept of a convergent and frequency reconfigurable architecture has been successfully demonstrated by applying radio over fiber technology in a geographically-distributed optical-wireless network. Experimental results of RF generation up to 10.4 GHz are presented, including high spectral purity RF carriers at 2.6 and 5.2 GHz with low phase noise and distortion absence.
