RECENT PROGRESS ON ASYNCHRONOUS COHERENT OCDMA (Invited Paper)

摘要：

In this paper, we review the recent progress in the key enabling techniques for asynchronous coherent OCDMA: the novel encoder/decoders including superstructured FBG (SSFBG) for ultra-long optical code processing and AWG type encode/decoder with very high power-contrast-ratio; optical thresholding techniques with PPLN and nonlinearity in fiber; The novel modulation format in OCDMA system: DPSK-OCDMA with balanced detection; and the applying of FEC in OCDMA system.Several multiuser asynchronous OCDMA experiments has been demonstrated including: The 10-user, gigabit OCDMA transmission experiment with 511-chip SSFBG and SC-based optical thresholder; The record throughput 12*10.71 Gbps OCDMA transmission using the 16*16 ports AWG-type encoder/decoder and FEC; The field trial of 3-WDM, 10-OCDMA, 10.71Gps WDM/DPSK-OCDMA using hybrid E/D.
