Abstract: | A novel approach to generate 60 GHz optical carrier suppression (OCS) millimeter-wave (mm-wave) signal based on the saturated
optical parametric amplification (OPA) effect in high non-linear fiber (HNLF) is investigated. In the proposed system, the
OPA effect occurs when the signal and pump with 30 GHz frequency interval are set into the high non-linear fiber. By controlling
the length of HNLF, OPA effect saturates, and the pump power is delivered in a large extent to the signal and idler light,
so a 60 GHz OCS mm-wave is generated. The system does not need high-speed external modulator, high-frequency vibration source
or narrow-band filter, which greatly reduces the cost and improves the stability of the radio over fiber (ROF) system. Results
show that the 10 Gb/s downstream signal can be transmitted with negligible power penalty. |
