NiO-MOF polyhedral particles were prepared and applied to ultrafast photonics, achieving a modulation depth of 18.98% and realizing 109th harmonic solitons for the first time. A compact mode-locked fiber laser with pulse duration of 766 fs and repetition frequency of 413 MHz was demonstrated with NiO-MOF, marking the first application of NiO-MOF for harmonic mode-locking at frequencies exceeding 400 MHz.
As a member of organic porous crystal structure, metal organic frameworks (MOFs) material has more unique properties due to its large specific surface area, high porosity, diversified structure and functions, it has been successfully applied in new energy, microelectronics, chemical reaction medical science and other fields. However, no study about NiO-MOF for the ultrafast optics application has been reported till now. In this paper, NiO-MOF polyhedral particles is prepared by hydrothermal method and successfully applied to ultrafast photonics. The modulation depth of NiO-MOF is 18.98 % through a dual-balance detection system. Most importantly, the 109th harmonic solitons are realized for the first time based on NiO-MOF in a compact mode-locked fiber laser at 1.55 mu m, the fiber laser has pulse duration of 766 fs and repetition frequency of 413 MHz. As far as we know, this is the first time NiO-MOF has been applied to realize harmonic mode-locking at the fs level of more than 400 MHz. Due to the rich variability of MOFs structure, this study successfully provides support for the application of MOFs material in advanced photonics.
