OSNR monitoring of a 1.28 Tbit/s signal using a reconfigurable Wavelength Selective Switch
OSNR monitoring reconfigurable Wavelength Selective Switch
2015/5/25
We demonstrate in-band optical signal to noise monitoring of an 1.28 Tbit/s signal by implementing an interferometer inside a reconfigurable wavelength selective switch based on liquid crystal on sili...
Stimulated Brillouin Scattering based In-Band OSNR Monitoring for 40G and 100G Deployment in Optical Networks with 100 GHz and 50 GHz Channel Spacing
Fiber optics communications Fiber optics links subsystems
2015/6/10
We present an improved approach for SBS based in-band OSNR monitoring with a drastic enhancement of the dynamic monitoring range for 44.6 Gbps DPSK and 112 Gbps DP-QPSK signals by intentionally adding...
OSNR Monitoring Using Two Fiber Interferometers
Fiber optics communications Phase modulation
2015/6/10
In-band OSNR from 5 to 30dB of a single 10G NRZ-OOK channel was measured by two fiber interferometers within an accuracy of ±0.5dB without requirement for knowledge of the noise-free extinction ratio ...
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...
OSNR Monitoring Technique for PDM-QPSK Signals Based on Asynchronous Delay-Tap Sampling Technique
Fiber optics communications Fiber optics links subsystems
2015/6/4
We propose and demonstrate a new technique for monitoring the individual OSNR of each polarization tributary of PDM-QPSK signals. The results show that the performance of this technique is not sensiti...

In-Band OSNR Monitoring Slow-Light Enhanced Third Harmonic Generation Silicon Photonic Crystal Waveguides
2015/7/16
We demonstrate optical performance monitoring of in-band OSNR in 40Gbit/s Return-to-Zero signals via slow-light enhanced third-harmonic generation in silicon photonic crystal waveguides, improving on ...
