Published in 2020 at "Laser Physics Letters"

DOI: 10.1088/1612-202x/ab63da

Abstract: The formation of stable single solitons and various bound states based on a graded index multimode fiber (GIMF) is investigated experimentally for the first time. Taking advantage of the principle of nonlinear multimode interference, a… read more here.

Published in 2022 at "Applied optics"

DOI: 10.1364/ao.471795

Abstract: A modal interferometer method (MIM) is applied to measure the differential mode delay (DMD) between the L P 0m modes traversing a step-index multimode fiber (SI-MMF). Only linearly polarized radial modes, i.e., L P 0m modes,… read more here.

DOI: 10.1364/oe.422667

Abstract: In this paper, we investigated the geometric parametric instability (GPI) in graded-index multimode fibers through the multimode generalized nonlinear Schrödinger equation. Our results clearly and intuitively indicate that the generations of GPI sidebands are nearly… read more here.

Published in 2022 at "Optics express"

DOI: 10.1364/oe.468095

Abstract: Photonic switches have attractive application prospects in optical communication data networks that require dynamic reconfiguration. Integrating optical switching devices with optical fiber, the most widely deployed photonic technology platform, can realize signal transmission and processing… read more here.

Published in 2023 at "Optics express"

DOI: 10.1364/oe.480398

Abstract: We report on the multidimensional characterization of femtosecond pulse nonlinear dynamics in a tellurite glass graded-index multimode fiber. We observed novel multimode dynamics of a quasi-periodic pulse breathing which manifests as a recurrent spectral and… read more here.

Published in 2018 at "Optics letters"

DOI: 10.1364/ol.43.002078

Abstract: A novel mode-locking method based on the nonlinear multimode interference in the stretched graded-index multimode optical fiber (GIMF) is proposed in this Letter. The simple device geometry, where the light is coupled in and out… read more here.
