摘要
在色散光纤传输系统中,调制产生的半导体激光波长移动(即啁啾)被证明对高比特率是一个严重的限制因子。本文导出了啁啾激光脉冲经色散光纤传输后的畸变波形,以此为基础讨论了避免啁啾光脉冲被光纤展宽的各种方法。
Abstract It is found that the transmission rate is limited by the wavelenth shift (chirp) induced with direct modulation of semiconductor laser in dispersive optical fiber system. In this paper, the distorted pulse shape is derived in the chirp pulse transmission through dispersive optical fiber ,and the methed is given for the chirp pulse not to be widened.
