VPIphotonics at 2017 Summer Conferences

NGON 2017

NGON 2017 - 19th Next Generation Optical Networking

June 20 - 22, 2017 in Nice (France)

VPIphotonics will attend and sponsor NGON 2017.

The 19th annual Next Generation Optical Networking event is the most important optical conference in Europe. 750+ professionals from the entire optical networking ecosystem from service providers, data centre operators all the way to the system vendors and component vendors. With the combination of 110+ service providers and all the leading optical networking vendors in attendance, the opportunity was seized by all to meet and network with all the right people to discuss the current challenges for the industry and discover and highlight the solutions for these challenges going forward.

Efficient modeling of doped fiber lasers

Session NOA I – paper We.C5.2 (tutorial):

Wednesday, July 5, 13:25-15:25

I. Koltchanov

Abstract: The presentation will provide an introduction to the theory of the doped fibers including equations for the doping ions' levels populations and radiation in the stationary and dynamic cases. After that, the modeling techniques required to simulate laser cavities in both frequency and time domains will be discussed. Furthermore, it will be shown how combining the fiber and cavity models, as well as the models for other active/passive laser components enables simulation and design of important cw and pulsed fiber lasers, in particular, high-power cladding-pumped lasers, fiber lasers for sensing applications, Q-switched and mode-locked fiber lasers.

GPU-assisted simulations of SDM systems

Session ICTON XI SDM – paper We.D1.6 (invited):

Wednesday, July 5, 15:25-17:55

A. Uvarov, N. Karelin, I. Koltchanov, A. Richter, H. Louchet, G. Shkred

Abstract: Spatial-Division Multiplexing (SDM) technology is aimed at overcoming capacity limits of single-mode transmission links. Design and characterization of such ultra-high capacity systems requires numerical techniques capable of dealing with vast amounts of data simulating nonlinear transmission and interaction of signals propagating in numerous spatial channels at different wavelengths, thus imposing serious challenges with respect to both memory requirements and computation performance. In this paper we discuss how massive-parallel computation capabilities of modern Graphical Processing Units (GPUs) can be utilized to develop efficient numerical algorithms and present assessment results for the GPU-assisted SDM-capable implementation in our simulator.

Prediction of accumulated DGD evolution for PMD-resistant Digital Back Propagation

Poster Session I – paper Tu.P.8:

Tuesday, July 4, 13:30-15:30

K. Goroshko, H. Louchet, A. Richter

Abstract: In this paper, we thoroughly investigate how evolutions of accumulated differential group delay along the fiber link depend on the fiber polarization mode dispersion coefficient (PMDc). We show that PMD statistics is important for simulating nonlinearity-PMD interactions and results depend on the way the PMD statistics is chosen. The results are demonstrated for the PMD-affected conventional ideal digital back propagation (DBP) and for the PMD-resistant modified version of DBP.

Unrepeated transmission of 28Gbaud PM-16QAM over 420km enabled by digital nonlinear pre-compensation

Poster Session

S.M. Bilal, K. Goroshko, H. Louchet, I. Koltchanov, A. Richter

Abstract: We demonstrate the superiority of digital nonlinear pre-compensation over post-compensation for unrepeated single-carrier 28Gbaud PM-16QAM Raman-amplified system. We show that transmitter side digital-back-propagation (DBP) combined with optimized Raman pump configurations enables unrepeated transmission over 420 km.

Analysis of Nonlinear Interference Noise in Flexible Optical Networks

Poster Session

S. Dris, H. Louchet, A. Richter

Abstract: An accurate statistical picture of nonlinear noise in WDM systems deployed over non-dispersion-managed, lumped amplification optical links is obtained via simulations. We separately assess intra- and inter-channel effects, allowing comparison with analytical models. Our method also discerns between additive and phase components of the noise.
