Description

technical field [0001] Based on the local light field enhancement and zero backscattering characteristics of dielectric silicon nanoparticles, the invention provides a dielectric silicon photonic crystal fiber and a manufacturing method thereof. Background technique [0002] Photonic crystal fiber, also known as microstructured fiber, was first proposed by Russell in 1992, and its light guiding performance was theoretically verified by Birks in 1995, and it was successfully prepared for the first time in 1999. It can realize the spatial modulation of optical signals through subwavelength periodic microstructures. In recent years, it has attracted extensive attention and developed rapidly in the fields of nonlinear optics, laser-induced transmission, biomedical imaging, optical sensing, and quantum optical devices. In the future, this technology will open up more research directions in other scientific research and engineering fields, and it is urgent to expand its applicatio...
