Orderly Arrangement

The new nonlinear optical material SrZnSnS4 is a two-dimensional layer structure with a large band gap (3.37 eV). The orderly arrangement of [ZnS4]6− and [SnS4]4− groups mainly contribute to the second harmonic generation effect (∼LiGaS2).

Nonlinear Optical Process

Here, we propose a novel plasmonic structure, called asymmetric plasmonic nanocavity grating (APNCG), which is shown to dramatically enhance nonlinear optical process of second harmonic generation (SHG). The proposed structure consists of two different metals on both sides of lithium niobate and a thin layer of graphene. By using two different metals the nonlinear susceptibility of the waveguide would be increased noticeably causing to increase SHG. On the other hand, it consists of two identical gratings on one side. By two identical gratings, the pump beam is coupled to two opposing SPP waves, which interfere with each other and result in SPP standing wave in the region between the two gratings. The distance between two gratings will be optimized to reach the highest SHG. It will be shown that by optimizing the geometry of proposed structure and using different metals, field enhancement in APNCG waveguides can result in large enhancement of SHG.

Property A

NIR-PDT strategy was introduced by employing a nonlinear optical conveyor bearing strong second-harmonic generation (SHG) property. A biocompatible micellic system co-delivered the conveyor and photosensitizer for in situ NIR-PDT.
