Accelerated Nonlinear Interactions In Graded-Index Multimode Fibers
Mohammad Amin Eftekhar,Z. Sanjabi-Eznaveh,Helena Lopez-Aviles,Sepehr Benis,Jose Enrique Antonio-Lopez,Miroslav Kolesik,Frank W. Wise,Rodrigo Amezcua-Correa,Demetrios N. Christodoulides +8 more
TL;DR: In this article, accelerated nonlinear intermodal interactions in core-diameter decreasing multimode fibers have been studied and shown to lead to relatively blue-shifted multimode solitons and blue-drifting dispersive wave combs, while in the normal domain, a notably flat and uniform supercontinuum, extending over 2.5 octaves.
Journal ArticleDOI
A systematic analysis of parametric instabilities in nonlinear parabolic multimode fibers
Helena Lopez-Aviles,Fan O. Wu,Z. Sanjabi Eznaveh,M. A. Eftekhar,Frank W. Wise,R. Amezcua Correa,Demetrios N. Christodoulides +6 more
TL;DR: In this article, the authors provide a systematic analysis of geometric parametric instabilities in nonlinear graded-index multimode fibers and show that the resulting parametric problem takes the form of a Hill's equation that can be systematically addressed using a Floquet approach.
Journal ArticleDOI
Observation of chiral state transfer without encircling an exceptional point
Hadiseh Nasari,Gisela Lopez-Galmiche,Helena Lopez-Aviles,Alexander Schumer,Absar U. Hassan,Q. Zhong,Stefan Rotter,P. Likamwa,Demetrios N. Christodoulides,Mercedeh Khajavikhan +9 more
TL;DR: In this paper , a fiber-based photonic emulator is used to observe the field evolution and chiral state conversion in an EP-excluding cycle in a slowly varying non-Hermitian system.
Journal ArticleDOI
Observation of twist-induced geometric phases and inhibition of optical tunneling via Aharonov-Bohm effects
Midya Parto,Helena Lopez-Aviles,Jose Enrique Antonio-Lopez,Mercedeh Khajavikhan,Rodrigo Amezcua-Correa,Demetrios N. Christodoulides +5 more
TL;DR: In this paper, it was shown that the tunneling or coupling process in a twisted multicore fiber system can display a chiral geometric phase accumulation, analogous to the Aharonov-Bohm effect.
Journal ArticleDOI
Topological Aharonov-Bohm suppression of optical tunneling in twisted nonlinear multicore fibers
Midya Parto,Helena Lopez-Aviles,Mercedeh Khajavikhan,Rodrigo Amezcua-Correa,Demetrios N. Christodoulides +4 more
TL;DR: In this paper, the authors show that the Aharonov-Bohm-like suppression of optical tunneling in twisted multicore fibers can persist even under highly nonlinear conditions.
