Abstract

Two-dimensional materials have extensively promoted the development of ultrafast photonics in the past decade. In our work, the saturable absorption properties of were presented. The saturation intensity, modulation depth, and nonlinear absorption coefficient of the saturable absorber (SA) are about 13.14/, 6.09%, and 1.85∗10/. In the experiment, based on the SA, two types of solitons were recorded. A conventional soliton with a pulse width of 985 fs and a three-pulse bound state soliton have been obtained. Our experiment reveals that can be employed for generating multiple ultrafast soliton generations and possess promising application in ultrafast photonics.

摘要

在过去十年中，二维材料极大地推动了超快光子学的发展。在我们的工作中，展示了[材料名称]的可饱和吸收特性。该可饱和吸收体（SA）的饱和强度、调制深度和非线性吸收系数分别约为13.14/[单位]、6.09%和1.85∗10/[单位]。在实验中，基于该[材料名称]SA，记录到了两种类型的孤子。获得了脉宽为985 fs的传统孤子和三脉冲束缚态孤子。我们的实验表明，[材料名称]可用于产生多个超快孤子，在超快光子学中具有广阔的应用前景。
