Abstract
Even in millimeter-wave-band (mm-wave-band) radio-on-fiber (ROF)
systems, wavelength-division multiplexing (WDM) combined with subcarrier
multiplexing (SCM) is a practical and attractive way to increase the
channel capacity in existing optical-frequency-interleaved fibers. In this
paper, we propose a channel selection scheme for interleaved dense WDM/SCM
mm-wave-band ROF signals that use optical heterodyne detection with
dual-mode local light. The principle underlying this scheme is explained
theoretically, and channel selection of the DWDM/SCM ROF signal after
transmission over a 25-km-long standard single-mode optical fiber has been
experimentally demonstrated.
