Published in 2021 at "Chinese Physics B"

DOI: 10.1088/1674-1056/abd68f

Abstract: We experimentally demonstrated a stable multi-wavelength bright–dark pulse pair in a mode-locked thulium-doped fiber laser (TDFL). The nonlinear polarization rotation (NPR) and nonlinear optical loop mirror (NOLM) were employed in a figure-eight cavity to allow… read more here.

Published in 2021 at "Physical Review A"

DOI: 10.1103/physreva.103.013513

Abstract: Dissipative Kerr solitons are localized structures that exist in nonlinear optical cavities. They lead to the formation of microcombs - chip-scale frequency combs that could facilitate precision frequency synthesis and metrology by capitalizing on advances… read more here.

Published in 2024 at "Journal of Lightwave Technology"

DOI: 10.1109/jlt.2024.3411590

Abstract: In this paper, we propose a feasible approach to generate a tunable dark-pulse comb with high coherence by injecting a beat-frequency pump into a standard normal-dispersion microring resonator. The optimized dark-pulse comb has a time… read more here.

Published in 2021 at "Optics letters"

DOI: 10.1364/ol.435668

Abstract: We theoretically demonstrate a novel, to the best of our knowledge, mechanism for dark pulse excitation in normal dispersion microresonators exploiting free carrier dispersion and free carrier absorption effects due to multi-photon absorption. Dark pulses… read more here.

Published in 2022 at "Optics letters"

DOI: 10.1364/ol.449715

Abstract: The temporal Talbot effect describes the periodic self-imaging of an optical pulse train along dispersive propagation. This is well studied in the context of bright pulse trains, where identical or multiplied pulse trains with uniform… read more here.
