preparation example Construction

[0040] figure 1 It is a flowchart of a method for manufacturing a metal core microstructure optical fiber according to the present invention. Such as figure 1 As shown, the present invention provides a kind of preparation method of metal core microstructure optical fiber, and this preparation method comprises the following steps:

[0041] A hollow capillary with openings at both ends is prepared from quartz glass;

[0042] Polish the metal rod smooth with sandpaper, and soak it in dilute nitric acid for an appropriate time to remove surface impurities, then take out the metal rod, rinse it and dry it naturally; put the metal rod after the above surface treatment such as gold rod, silver rod or copper rod The rod is put into a quartz glass sleeve with one end sealed, and then a metal core capillary is drawn through a wire drawing heating furnace; the temperature of the wire drawing heating furnace can be set according to the softening point of the quartz glass, for example, t...

Embodiment 1

[0049] Step 1: Use a quartz glass sleeve with an outer diameter of 27.5mm and a wall thickness of 10.3mm to make a hollow capillary with an outer diameter of 1.5mm and openings at both ends by drawing at 1800°C.

[0050] Step 2: Polish a silver rod with a diameter of 5mm, a length of 30cm, and a purity of 99.99% with sandpaper, and soak it in dilute nitric acid for 10-15 minutes to remove surface impurities, then take out the silver rod and rinse it with deionized water Then dry naturally. Put the silver rod after the above-mentioned surface treatment into a quartz glass casing with one end sealed. The outer diameter of the casing is 27.5 mm, and the inner surface is a regular hexagon with a side length of 4 mm. Then, the quartz glass sleeve with the silver rod suspended in the wire drawing heating furnace. A silver core capillary with an outer diameter of 1.5 mm was fabricated at 1800°C.

[0051] The third step: use a pure quartz glass rod with an outer diameter of 1.5mm as...

Embodiment 2

[0057] Figure 5 It is a structural schematic diagram according to Embodiment 2 of the present invention. In this embodiment, except that the first step uses a casing with a wall thickness of 11.4 mm, the second step uses a gold rod with a diameter of 3 mm, and the inner surface of the casing in the second step is a square hole with a side length of 4.8 mm, Others are the same as example 1.

[0058] Such as Figure 5 As shown, the cross-section of the wire-drawn metal core is rectangular. The side length of the metal core 1 and the diameter of the air hole 2 are both 500nm, the distance between adjacent metal cores is 3000nm, the material of the core 3 is pure quartz glass, and the material of the outer layer 4 is pure quartz glass.

[0059] Through research, when the cross-section of the metal core is rectangular, the confinement ability of the metal core microstructured optical fiber is stronger, and it has a high tolerance to the structural asymmetry caused by the manufa...
