Two-dimensional (2D) hybrid organic-inorganic perovskites (HOIPs) have aroused great interests in various optoelectronic fields. Here, the highly stable 2D (C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> H xmlns:xlink="http://www.w3.org/1999/xlink">5</sub> C xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> NH xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> ) PbI nanocrystals (PEA...
A stable mid-infrared saturable absorber with a high damage threshold is urgently required for high-performance optical modulation in the regime. Here, we demonstrate erbium-doped fiber laser generation modulated by tantalum carbide nanoparticles (TaC NPs) experimentally. The TaC NPs show physicochemical stability, obvious nonlinear absorption, and threshold. By introducing TaC-based into an laser, nanosecond pulses can be successfully delivered minimum pulse duration of 575 ns...
The broadband nonlinear optical modulators (NLOMs) are highly required for the versatile optoelectronic applications, especially towards mid-infrared (mid-IR) regime. Transition metal pentatelluride (TMP), typical Dirac semimetal, has attracted great attention due to its unique physicochemical properties, which make it an ideal candidate devices. Here, we prepared HfTe5 and ZrTe5 nanosheets by liquid-phase exfoliation (LPE) method experimentally demonstrated their ultra-broadband modulation...
