TL;DR: In this article, the authors compared the performances of optical millimeter-wave generation or up-conversion using external modulators based on different modulation schemes and found that the OCS modulation scheme has the highest receiver sensitivity, highest spectral efficiency and smallest power penalty over long-distance delivery.

TL;DR: Several key enabling technologies for hybrid optical-wireless access networks are described, including optical millimeter-wave (mm-wave) generation, upconversion, and transmission in a downlink direction, and full-duplex operation based on wavelength reuse by using a centralized light source in an uplink direction.

TL;DR: In this paper, the authors proposed a converged WDM-PON architecture for longer reach, higher data rate, and higher spectral efficiency for single-source systems and integrated the integrated schemes with radio-over-fiber (RoF)-based optical-wireless access systems to serve both fixed and mobile users in the converged optical platform.

TL;DR: In this paper, a full-duplex radio-over-fiber system using a single light source at the central station (CS) was demonstrated, where the optical carrier suppression modulation scheme was employed to generate 40GHz optical millimeter wave and up-convert the baseband signal simultaneously at CS for downlink transmission while the same optical carrier was reused at base station for uplink connection.

TL;DR: In this article, an optical signaling header (210) technique applicable to optical networks is proposed, where packet (620) routing information is embedded in the same channel or wavelength as the data payload (211) so that both the header (212) and data (211), respectively, propagate through network elements with the same path and associated delays.
