DOI: 10.1016/j.optcom.2017.02.020

Abstract: Abstract We study the effect of linear coupling on nonlinear phase noise in two-core fibers (TCFs). Considering the elementary TCF switching process, we demonstrate reduction of nonlinear phase noise in the propagation of optically amplified… read more here.

DOI: 10.1063/1.5111987

Abstract: A minimal model of nonlinear phase dynamics in drift waves is shown to support phase bore solutions. Coupled nonlinear equations for amplitude, phase, and zonal flow are derived for the Hasegawa-Mima system and specialized to… read more here.

DOI: 10.1109/jphot.2018.2799998

Abstract: Nonlinear phase noise (known as Gordon–Mollenauer phase noise) results from power fluctuations arising from amplified spontaneous-emission noise of the inline amplifier which is converted into phase fluctuations due to the self-phase modulation effect. It may… read more here.

DOI: 10.1109/jsen.2024.3458902

Abstract: The frequency-modulated continuous wave (FMCW) radar, employing a dechirp receiver structure, is widely favored for short-range imaging and ranging due to its simplicity, cost-effectiveness, and high resolution. However, inherent nonlinear errors degrade its imaging performance.… read more here.

DOI: 10.3390/a17120553

Abstract: Optical communication systems face challenges like nonlinear noises, particularly Kerr-induced phase noise, which worsens with higher-order m-QAM formats due to their dense data-symbol sets. Advanced signal processing, including machine learning, is increasingly used to enhance… read more here.
