摘要：
Methods of converting silica to silicon and fabricating silicon photonic crystal fiber (PCF) are disclosed. Silicon photonic crystal fibers made by the fabrication methods are also disclosed. One fabrication method includes: sealing silica PCF and a quantity of magnesium within a container, the quantity of magnesium defined by 2Mg (g) +SiO 2(s) →2MgO (s) +Si (s) ; converting silica PCF to a reacted PCF through magnesiothermic reduction; and converting the reacted PCF to the fabricated silicon PCF by selective dissolution of the reacted PCF in an acid. Another fabrication method includes: adding silica PCF and a quantity of solid magnesium to an unsealed container, the quantity of magnesium substantially in excess of that defined by 2Mg (g) +SiO 2(s) →2MgO (s) +Si (s) ; converting silica PCF to a reacted PCF through magnesiothermic reduction; and converting the reacted PCF to the fabricated silicon PCF by selective dissolution of the reacted PCF in an acid.
