摘　　要：A phase pre-emphasis technique used in an all-optical sampling orthogonal frequency division multiplexing （AOS-OFDM） system is proposed and demonstrated. With the application of this technique, 50-Gb/s AOS-OFDM data are successfully transmitted over 20-km uncompensated single-mode fiber （SMF） with real-time direct-detection. The constructive interference effect between symbols is decreased with this technique.A phase pre-emphasis technique used in an all-optical sampling orthogonal frequency division multiplexing （AOS-OFDM） system is proposed and demonstrated.
