Abstract

Germanium selenide nanoplates (GeSe NPs) are considered to have broadband nonlinear optical (NLO) properties and great potential for applications in nanophotonic devices. In this work, we systematically studied the NLO response of GeSe NPs by the open-aperture Z-scan technique. GeSe NPs exhibit strong saturable absorption at wavelengths of 400, 800, and 1064 nm with different pulse durations. Furthermore, we investigated the excited carrier dynamics of GeSe NPs by the non-degenerate pump-probe technique. The fast and slow relaxation times at different wavelengths of 800, 871, 1064, and 1100 nm were components with lifetimes of about 0.54–1.08 and 52.4–167.2 ps, respectively. The significant ultrafast NLO properties of GeSe NPs imply their potential in the development of nanophotonic devices. Here, we designed and fabricated the all-optical diode by means of the GeSe/C60 tandem structure and demonstrated that the saturable absorption behavior of GeSe NPs can be used to fabricate a photonic diode, which exhibits nonreciprocal transmission of light similar to that of an electron diode.

Abstract

Two dimensional (2D) ternary chalcogenides, a significant class of optoelectronic materials, exhibit distinctive structures and possess exceptional physical and chemical properties. In this study, a novel 2D ternary chalcogenide, Ta2NiTe5, is synthesized using the liquid‐phase exfoliation technique to create a high‐quality saturable absorber (SA). The nonlinear optical characteristics of the prepared Ta2NiTe5 nanosheets, ranging from 500 nm to 3.0 µm, are investigated using the P‐scan and open‐aperture Z‐scan methods. Furthermore, the stable passively Q‐switched lasers based on the Ta2NiTe5‐SA device are realized with a minimum pulse width of 326 ns, 2.18 µs, and 850 ns at 1.0, 2.0, and 3.0 µm wavelengths, respectively. The findings not only provide further evidence of the promising potential of 2D ternary chalcogenides as an SA for the achievement of broadband pulsed lasers, but also pave the way for promoting their potential applications in optoelectronic devices.

10. Near-infrared multiphoton absorption and third harmonic generation with CsPbBr3 quantum dots embedded in micro-particles of metal–organic frameworks.

Abstract

Materials with multiple nonlinear-optical responses have been investigated widely in recent years. Here, we report a hybrid system with both giant multiphoton absorption (MPA) and efficient third harmonic generation (THG) excited by near-infrared femtosecond laser pulses. The hybrid material consists of both CsPbBr3 quantum dots and metal–organic framework microparticles. The two-, three-, four-, and five-photon absorption cross-sections of the hybrid material are three orders of magnitude greater than those of CsPbBr3 micro-crystals. The effective χ(3) values are three orders of magnitude greater than those of α-quartz. Our findings demonstrate a new avenue to realize photo-stable, high-order MPA, and THG in microparticles synthesized using a cost-effective method. [ABSTRACT FROM AUTHOR]

Abstract

Multiphoton absorption may find many technological applications, such as enhancing the conversion efficiency of solar cells by the utilization of sub‐band‐energy photons, below‐bandgap photodetection through the simultaneous absorption of several infrared photons for photocurrent generation, or light frequency upconversion for high‐resolution, 3D imaging. To enhance multiphoton absorption in semiconducting materials, one of the strategies is to explore low‐dimensional excitons. Here, a quantum perturbation theory on a giant enhancement in three‐photon absorption (3PA) arising from 2D excitons in multilayered crystals of organic–inorganic hybrid perovskites is presented. The maximal 3PA coefficient is predicted to be in the range of 2–7 cm3 GW−2 at 1100 nm, the largest values reported so far for any 2D and bulk semiconductors at room temperature. Excellent agreement between theory and the experimental findings unambiguously demonstrates a pivotal role in the enhancement of 3PA played by 2D excitons. The theory predicts that the resonant 3PA coefficient should be enhanced further by at least two orders of magnitude with very low temperature. The findings are essential for understanding giant 3PA arising from 2D excitons in layered hybrid perovskites and may open new pathways for highly efficient conversion from infrared light energy to either electrical energy or higher‐frequency light emission/lasing. Here, a giant enhancement in three‐photon absorption (3PA) arising from two‐dimensional (2D) excitons is theoretically predicted and experimentally observed in multi‐layered crystals of organic–inorganic hybrid perovskites. This finding is essential for understanding 3PA in layered hybrid perovskites and may open new pathways for highly‐efficient conversion from infrared light energy to either electrical energy or higher‐frequency light emission/lasing.
