Experimental studies of the combined nonlinear and PDL effects reveal that interplay between fiber nonlinearity and PDL changes the shape of the Q-distribution, which becomes narrower and asymmetric, depending on system parameters.
Dependencies on segment number, dispersion map, and fibre launched power were investigated experimentally and numerically. Uncompensated 25 spans standard SMF link can enjoy net Q gain of 1.7 dB with 25 segments compensation.
We present a novel method to monitor and adaptively optimize digital carrier phase estimation in optical coherent receivers. This guarantees the optimal performance irrespective of the differences and changes in devices and transmission channels.
Hybrid simulation was performed to analyze the response of the real-time reflection-type radio frequency single-electron transistor (RF-SET) measurement system. A compact and physically-based analytical SET model, which was validated with a Monte Carlo simulator, was used to simulate the SET characteristics, while SPICE equivalent circuits were implemented to simulate all other components of the RF-SET...
