Efficient graphene saturable absorbers on D-shaped optical fiber for ultrashort pulse generation

Juan Diego Zapata Caro, +5 more
TL;DR: In this paper, a method to construct high efficiency saturable absorbers based on the evanescent light field interaction of CVD monolayer graphene deposited on side-polished D-shaped optical fiber was demonstrated.
Journal ArticleDOI

Mitigation of time-varying distortions in Nyquist-WDM systems using machine learning

Jhon James Granada Torres, +6 more
- 01 Nov 2017 - 
TL;DR: 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 is proposed.
Proceedings ArticleDOI

Adaptive nonsymmetrical demodulation based on machine learning to mitigate time-varying impairments

Jhon James Granada Torres, +5 more
TL;DR: Experimental results showed that nonsymmetrical demodulation can reduce the SER by up to 0.7 decades, when assuming time frames consisting of 10 k symbols and fiber transmission of 250 km.
Proceedings ArticleDOI

Demodulation of m-ary non-symmetrical constellations using clustering techniques in optical communication systems

Eduardo Avendaño Fernández, +3 more
TL;DR: In this paper, clustering techniques such as k-means and Fuzzy c-Means (FCM) are applied for phase recovery and demodulation of m-ary non-symmetrical constellations, distorted by linear and nonlinear impairments in optical fiber transmission systems.
Proceedings ArticleDOI

Evaluation and compensation of interchannel interference effects in a 16-QAM Nyquist-WDM system with LMS equalization

Jhon James Granada Torres, +2 more
TL;DR: The performance of the Nyquist-WDM systems is improved with LMS equalization, reducing the log(BER) from -1 to -11 for 5 km in a channel spacing equal to the symbol rate, and from ~2 to ~20 for aChannel spacing penalty of 1.5 GHz, which is feasible in practice in the pulse shaping filter at the transmitter.
