    ABSTRACT: When we fabricated the Micro-structure Fiber (MSF) in hexagon structure by stacking round capillaries, there must be a hole that looks like an equilateral triangle among every three adjacent capillaries. It is called the interstitial hole. We discuss the transformation of the interstitial hole during the fabrication of the MSF. The result shows that, when ΔP = 0, the interstitial hole will be hold after drawing the perform; and if ΔP ≠ 0 the capillaries in the cladding will expand, and the interstitial hole will be eliminated (ΔP is the pressure difference between the capillary and the interstitial hole). According to the result, we fabricate the MSF by controlling the AP. The experiment result is the same as the analyses result. With this method, we can fabricate the MSF without the interstitial hole, and this will help to keep the cladding's structure, and enhance the stability of the fabrication.

    ABSTRACT: We describe an improved stacking-capillary method, which can fabricate the microstructure fiber (MSF) without interstitial holes. This method includes several steps. Firstly, the MSF preform is made by the stacking-capillary method, and we heat one side of the preform in order to make the capillary close; secondly, the MSF preform is put into the high temperature furnace to heat at 1600°C; then the positive pressure is produced into the capillaries by adding air, every three adjacent capillary holes are expanded in the preform, so the interstitial holes are eliminated, and all the capillaries are fused together. It is helpful to keep the MSF structure during drawing fiber. We get well experimental results by the improved stacking-capillary method.
