Structure formation dynamics in drawing silica photonic crystal fibres

Abstract

The special features of photonic crystal fibres (PCFs) are achieved by their air hole structures. PCF structure is determined and formed by its origin preform design and drawing process. Therefore, structure formation dynamics in drawing PCF is important for the fabrication of PCF achieving desirable structure and thus the intended feature. This paper will investigate structure formation dynamics of PCF drawing in relation to key parameters and conditions, such as hole dimension, temperature, pressure, etc.

Overview of 3D-Printed Silica Glass

“…The application of the DLP process to the preparation of optical fibers and microfluidic channels simplifies the preparation process and enables the application of 3D printing in the field of optics and microfluidic channels [86][87][88][89]. DLP has been widely applied and reported, and its advantages are outstanding, although the disadvantage that the preparation of multi-material structures is not able to be realized in one step is still obvious.…”

Multiparameter-detecting biosensors based on the surface and waveguide modes of the two-dimensional photonic crystal slab

“…Photonic crystals (PhCs) [5,6] are formed by periodically arranging different materials at the scale of wavelength, which can prohibit the propagation of light beam within a certain frequency scope and it is known as photonic bandgap (PBG). The PhC defects (formed by changing the shape, size and position of the scattereres at certain region) can localize photons and form the localized modes at the particular frequencies within PBG, and it is extensively applied in various optical devices, such as waveguides [7,8], splitters [9][10][11], filters [12,13], sensors [14][15][16][17]. In recent years, the biosensors based on PhC defects have attracted much attention due to their advantages of high sensitivity, fast response, no label, no pollution, high selectivity, high safety and so on [18,19].…”
