研制了一台1.55μm InGaAsP-InP部分增益耦合的变脊宽两段DFB自脉动激光器。该激光器产生频率调谐范围超过135 GHz的自脉动。从40 Gb/S降质数据流中实现了全光时钟恢复。成功地锁定了30 GHz、40 GHz、50 GHz和60 GHz频率下的10 GHz边模注入,验证了该器件在不同频率下的全光时钟恢复能力。该装置的这种灵活性是实际应用中非常需要的。
A 1.55μm InGaAsP-InP partly gain-coupled two-section DFB self-pulsation laser (SPL) with a varied ridge width has been fabricated. The laser produces self-pulsations with a frequency tuning range of more than 135GHz. All-optical clock recovery from 40Gb/s degraded data streams has been demonstrated. Successful lockings of the device at frequencies of 30GHz, 40GHz, 50GHz, and 60GHz to a 10GHz sidemode injection are also conducted, which demonstrates the capability of the device for all-optical clock recovery at different frequencies. This flexibility of the device is highly desired for practical uses.
