A PMD-adaptive DBP receiver based on SNR optimization
- 2018
-
Ingår i: Optics InfoBase Conference Papers. - 2162-2701. - 9781943580385
-
Konferensbidrag (refereegranskat)abstract
- We propose a novel adaptive digital backpropagation (DBP) scheme that tracks the fiber polarization-mode dispersion via the optimization of the signal-to-noise ratio. Gains of up to 1.4 dB over conventional DBP are achieved.

Phase-Noise Compensation for Spatial-Division Multiplexed Transmission
- 2017
-
Ingår i: Optics InfoBase Conference Papers. - 2162-2701.
-
Konferensbidrag (refereegranskat)abstract
- The problem of correlated phase noise in spatial-division multiplexed transmission is studied. To compensate for the phase noise, an algorithm for joint-core phase-noise estimation and symbol detection is proposed, which outperforms conventional methods.

THz emissions by two-color filaments in air: Revisiting the wavelength scaling
- 2019
-
Ingår i: Optics InfoBase Conference Papers. - 2162-2701. ; Part F134-NLO 2019
-
Konferensbidrag (refereegranskat)abstract
- We report impressive growths in the terahertz energies supplied by air plasmas created by two-color laser pulses whose fundamental wavelength is increased. Comprehensive 3D simulations reveal the crucial role of the two-color relative phase.

ASIC Design Exploration of Phase Recovery Algorithms for M-QAM Fiber-Optic Systems
- 2019
-
Ingår i: Optics InfoBase Conference Papers. - 2162-2701. - 9781943580538
-
Konferensbidrag (refereegranskat)abstract
- We develop circuit implementations and explore design optimizations for one blind and one pilot-based carrier phase-recovery algorithm, where the former algorithm is shown to dissipate 1.8-4.5 pJ/bit and the latter 0.5-0.3 pJ/bit, using 16 to 256QAM.

-
Konferensbidrag (refereegranskat)abstract
- This paper summarizes recent research on 5G transport networks addressing challenges on capacity, service migration and techno-economics that are brought by 5G new attributes, e.g., cloud radio access networks, diverse usage scenarios and heterogeneous deployments.

Modal Dynamics in Spatially Multiplexed Links
- 2019
-
Ingår i: Optics InfoBase Conference Papers. - Washington, D.C. : OSA. - 2162-2701.
-
Konferensbidrag (refereegranskat)abstract
- We investigate the vibration sensitivity of spatially multiplexed links by measuring the mode-coupling dynamics of a four-core coupled-core fiber and a reference single-mode fiber. We show that the speed of dynamics increases with mode count.
