Abstract

A phase adjustment technique employing optical spectrum processing is proposed to suppress the dispersion induced phase noise (PN) in optically generated millimeter-wave (MMW) and fiber transmission. A phase shift between the two beating optical tones in an optical MMW link is introduced by an optical spectrum processor (OSP) to compensate the phase mismatch between them, which results from fiber dispersion and deteriorates the PN of optically generated MMW signals. A MMW PN amelioration of 12.63 dB at 10 kHz offset and 11.23 dB at 100 kHz offset is achieved in a 40 GHz, 25 km optical MMW link thanks to this OSP.
