We demonstrate how loss-optimised, gain-saturated SOA-REAM based reflective modulators can reduce the burst to burst power variations due to differential access loss in the upstream path in carrier distributed passive optical networks by 18 dB compared to fixed linear gain modulators. We also show that the loss optimised device has a high tolerance to input power variations and can operate in deep saturation with minimal patterning penalties. Finally, we demonstrate that an optimised device can operate across the C-Band and also over a transmission distance of 80 km.
我们展示了基于损耗优化、增益饱和的半导体光放大器(SOA)-反射型电吸收调制器(REAM)的反射调制器如何能够将载波分布式无源光网络中上行链路因差分接入损耗导致的突发到突发功率变化,与固定线性增益调制器相比降低18分贝。我们还表明,损耗优化后的器件对输入功率变化具有高耐受性,并且能够在深度饱和状态下工作,且具有最小的图案化代价。最后,我们证明了优化后的器件能够在整个C波段以及80公里的传输距离上工作。
