Autor: Stephen E. Ralph, Varghese A. Thomas, Ana Maria Cardenas Soto, Andrea Chiuchiarelli, Neil Guerrero González, Jhon James Granada Torres, Siddharth Varughese

Publikováno v: Optical Fiber Technology. 38:130-135

We propose a machine learning-based nonsymmetrical demodulation technique relying on clustering to mitigate time-varying distortions derived from several impairments such as IQ imbalance, bias drift, phase noise and interchannel interference. Experim

Optical Frequency Comb Generation based on MZM for Elastic Optical Networks

Autor: Daniel Sánchez, Jhon James Granada Torres, Ana Maria Cardenas Soto

Publikováno v: 2019 IEEE Colombian Conference on Communications and Computing (COLCOM).

In this paper, we present a comb generation conformed by twenty one subcarriers with a fixed space, following the ITU-T G.694.1 recommendation for Elastic Optical Networks. This generation is done through optical frequency comb generator (OFCG) using

Adaptive Phase-Offset Compensation on Fragmented Constellation Diagrams in Radio-over-Fiber Systems

Autor: Giovanni Serafino, Francesco Fresi, Ana Maria Cardenas Soto, Neil Guerrero González, Antonella Bogoni, Eduardo Avendaño Fernández

Publikováno v: Latin America Optics and Photonics Conference.

A phase-offset compensation by dual-stage ring fragmentation and clustering of 16-QAM and APSK constellation is demonstrated experimentally in RoF scenario. OSNR improvements of 3.3 dB and 1.4 dB for 16-QAM and 12+4 PSK, respectively, are obtained.
