摘要： This paper reports optical orthogonal frequency-division multiplexing (OFDM) transmission using 850nm Zn-diffusion Vertical-Cavity Surface-Emitting Lasers (VCSELs) and multimode fiber (MMF) for small-cell backhaul applications. We also investigated the influence of side mode suppression ratio (SMSR) on the performance of OFDM modulation. By further optimizing the Zn-diffusion conditions and oxide aperture size, a high-power (6.7mW) SM (SMSR>30dB) VCSEL is demonstrated. By using OFDM modulation and bit-loading algorithm, record-high BRDP (91Gb/skm) at 26Gb/s transmission under FEC threshold (bit error rate (BER)<3.8×10−3) across 3.5km OM4 fiber has been successfully demonstrated. 出版者： Elsevier B.V 出版日期： 2015-07-15 出處： Optics communications, 2015-07, Vol.347, p.81-87 資源來源： Elsevier Journals King’s College London Perpetual Access 版權： 2015 Elsevier B.V. 識別號： ISSN: 0030-4018 識別號： EISSN: 1873-0310 識別號： DOI: 10.1016/j.optcom.2015.03.004
