Wide Dynamic Range of Ring Resonator Channel-Dropping Filters with Integrated SOAs
Integrated SOA Ring Resonator Channel-Dropping Filters Wide Dynamic Range
2015/5/15
We present the first complete simulation of the dynamic range and noise of InGaAsP multi-ring channel-drop filters with internal SOAs. The results show gain saturation, and spontaneous emission noise ...
Wide Dynamic Range OSNR Monitoring for RZ-DQPSK Systems using Delay-Tap Sampling Technique
Fiber optics communications Fiber optics links subsystems
2015/6/5
We propose half-symbol delay-tap sampling for OSNR monitoring and extend the monitoring range to 5−45 dB. The proposed method also enables calibration-free monitoring with range of 16−43 d...
