Dispersion map optimization for nonlinearity mitigation in two-span phase-sensitive amplifier links
- 2016
-
Ingår i: 42nd European Conference on Optical Communication, ECOC 2016; Dusseldorf; Germany; 18 September 2016 through 22 September 2016. - 9783800742745 ; , s. 953-955
-
Konferensbidrag (refereegranskat)abstract
- The first investigation of dispersion map optimization in two-span PSA-amplified links is presented. We show numerically and experimentally, that the nonlinearity mitigation improves by 1.4 dB if different dispersion maps are applied in each span, compared to single-span optimized maps.

Kerr frequency combs in a bichromatically pumped nonlinear fiber ring cavity

-
Konferensbidrag (refereegranskat)abstract
- We report numerical and experimental studies of four-wave mixing processes emerging from dual-frequency pumping of a passive fibre ring cavity. We observe the emission of a periodic train of nearly-background-free soliton pulses associated with Kerr frequency combs.

Polarization-Mode Dispersion Aware Digital Backpropagation

-
Konferensbidrag (refereegranskat)abstract
- We study a modified DBP algorithm that accounts for PMD. Based on the accumulated PMD at the receiver, the algorithm distributively compensates for PMD in the reverse propagation and outperforms the conventional approach by up to 2.1 dB.

Nonlinear-Impairments- and Crosstalk-Aware Resource Allocation Schemes for Multicore-Fiber-based Flexgrid Networks
- 2016
-
Ingår i: ECOC 2016; 42nd European Conference on Optical Communication; Proceedings of. - 9783800742745
-
Konferensbidrag (refereegranskat)abstract
- Abstract: In this study, we propose a novel spectrum and core allocation scheme that incorporates both intra-core physical layer impairments and inter-core crosstalk. We demonstrate that accounting for the latter increases spectral efficiency by at least 50% when crosstalk is significant.

Ultra-Wideband Nonlinearity Compensation Performance in the Presence of PMD
- 2016
-
Ingår i: 42nd European Conference on Optical Communication, ECOC 2016; Dusseldorf; Germany; 18 September 2016 through 22 September 2016. - 9783800742745 ; , s. 794-796
-
Konferensbidrag (refereegranskat)abstract
- We investigate the performance of multi-channel digital backpropagation for 1 THz bandwidth optical fibre transmission in the presence of polarisation-mode dispersion. We show that the average SNR performance rapidly saturates as a function of the compensation bandwidth.

Power Consumption of a Minimal-DSP Coherent Link with a Polarization Multiplexed Pilot-Tone
- 2016
-
Ingår i: 42nd European Conference and Exhibition on Optical Communications, September 18-22, 2016, Düsseldorf. - 9783800742745
-
Konferensbidrag (refereegranskat)abstract
- We experimentally study the trade-off between performance and DSP power consumption. While minimal DSP allows transmission of 16QAM at 5 GBaud, the symbol rate can be increased if anextra equalizer is added, leading to energy savings in optical components.

Measurement of Temperature-Induced Polarization Drift and Correlation in a 7-Core Fiber

-
Konferensbidrag (refereegranskat)abstract
- We study the correlation in polarization drift between different cores of a 7-core fiber subjected to temperature fluctuations. We present a method to quantify these changes and show that the drift in different cores is correlated to 98%.

-
Konferensbidrag (refereegranskat)abstract
- We propose an agile and programmable multicore fiber (MCF)-based filterless network that exploits the flexibility offered by spatial domain multiplexing and programmable optical switches to eliminate the waste of spectrum due to unfiltered transmission.
