QPSK Training Sequence-Based Both OSNR and Chromatic Dispersion Monitoring in DWDM Systems

IEEE Photonics Journal, 2018
We design a quadrature phase-shift keying training sequence (QPSK-TS) for monitoring both optical signal-to-noise ratio (OSNR) and chromatic dispersion (CD) in a dense wavelength division multiplexing (DWDM) system.

HeCSON: Heuristic for Configuration Selectionin Optical Network Planning

, 2020
We present a transceiver configuration selection heuristic combining Enhanced Gaussian Noise (EGN) models, which shows a 40\% increase in throughput and 87\% decrease in execution time, compared to only approximate EGN and Full-Form EGN ...

All-optical reconfigurable non-inverted logic gates with a single semiconductor optical amplifier

AIP Advances, 2019
All-optical reconfigurable non-inverted logic gates with a single semiconductor optical amplifier (SOA) is proposed. Compared with the probe light of continuous light, the clock (Clk) pulse sequences light is regarded as the probe light so that the ...
