“…The OC divided the output laser and pump source into two paths after passing through WDM and EDF. One part of optical power is directed into the Au NP-SA sample, while the other part of optical power serves as a reference value [24]. By incorporating a reference arm next to the Au NPs-SA sample, comparative analysis can be performed, facilitating accurate measurements and ensuring the reliability and significance of obtained results.…”

The Au ion implantation process has emerged as an effective and simple method to be utilized for the fabrication of opto-electronic materials and devices due to numerous fascinating features of Au nanoparticles such as surface plasmon resonance (SPR), large third-order nonlinearity and a fast response time. In this paper, we describe the fabrication of a novel Au nanoparticle saturable absorber (Au NP-SA) by embedding the Au NPs into a SiO2 thin film using the ion implantation process, which shows excellent saturable absorption features due to the localized surface plasmon resonance (LSPR) effect of Au NPs. A stable and high-quality pulsed laser with a repetition rate of 33.3 kHz and a single pulse energy of 11.7 nJ was successfully constructed with the Au NP-SA. Both the stable operation characteristic of the obtained Q-switched pulsed laser and the high repeatability of the fabrication process of the Au NP-SA were demonstrated. In addition, the simple feasibility and maturity of the ion implantation process allow for the plasmonic nanoparticles to be easily integrated into other types of opto-electronic materials and devices to further improve their performance, and shows immense potential for the production of wafer-level products.

“…At the same time, by constructing a SG-SAM-based ring cavity EDF laser, a passively mode-locked pulse operation with a pulse width of 830 fs is obtained. This work shows the potential application of graphene-based passive devices in the field of optoelectronics [ 2 ]. Lin et al, described an n-ReSe 2 /p-MoTe 2 vertical heterojunction broadband photodetector with an optical response speed of 5.6/4.2 ms.…”
