example 1

[0061] 34 capillary tubes of φ370mm*35mm are used, a solid rod of φ150mm is sandwiched in the center, and two conductive glass rods of φ370mm are positioned in the diameter direction of the outermost circumference. After the position is fixed, it is fixed with low-melting glass filaments, and then sleeved to form a photonic crystal structure.

[0062] The completed preform rod is drawn with a power of 4KW, and the diameter is controlled to be 125 microns, and then coated on the outside of the glass, and the diameter of the coated optical fiber reaches 245-250 microns.

[0063] To use this kind of fiber for fusion splicing experiments, first strip off the coating layer at one end of the fiber, and then install the fiber on the clamp of the fusion splicer; connect the other end of the fiber to the DC electrode. Set the fusion splicer to manual, align first, then approach, and observe the position of the two photonic crystal fibers under the lens to ensure that the error in the X...

[0065] A modified PMMA rod with a specification of φ450mm is used, and the prefabricated rod is processed according to the designed microholes, and two polyacetylene conductive polymer rods matching the diameter of the micropores are placed inside the microholes in the direction of the diameter of the outermost circumference. . After the position is fixed, the photonic crystal crystal prefabricated rod is made by thermal welding, and then drawn to form a photonic crystal structure. Control the diameter to meet the requirements.

[0066] To use this fiber for fusion splicing experiments, first install the fiber on the clip of the fusion splicer; connect the other end of the fiber to the DC electrode. Set the fusion splicer to manual, align first, then approach, and observe the position of the two photonic crystal fibers under the lens to ensure that the error in the X and Y directions is less than 0.3 microns, and the angle error of the end face is less than 10 degrees, and th...

Abstract

The invention discloses a conductivity property photon crystal optical fiber and preparing method, which is characterized by the following: setting optical fiber core layer (3), at least three layer arrangements of capillary (4) and quartz clad (1) sequently from inside to outside; distributing two conductivity poles (2) at point symmetry on the outer circumference of the most outside capillary (4); designing photon crystal; adapting conductivity material instead of photon crystal to prepare the conductivity pole (2); drawing wire.

Description

technical field [0001] The invention relates to optical communication materials, in particular to a new type of optical transmission medium and a photonic crystal fiber with electrical conductivity used in the laser field and a preparation method thereof. Background technique [0002] Photonic crystal fibers are an important invention of the last decade and are expected to replace conventional single-mode fibers in optical fiber communications. By definition, a photonic crystal is an optical material with a periodically changing refractive index, and its period is comparable to the wavelength of light. According to the definition of photonic crystal, it can be divided into two types: total internal reflection principle photonic crystal fiber (TIR-PCF) and photonic bandgap effect principle photonic crystal fiber (PBG-PCF). The characteristics of this new type of fiber include: [0003] 1. Its light guiding mechanism is different from that of conventional optical fibers: [...
