Résumé

The development of transparent optical fibers represents one of the biggest scientific challenges for a wide variety of modern technologies ranging from communication systems to medical applications. Here, transparent Sr3Al2O6 crystalline fibers have been grown by the laser-heated pedestal growth (LHPG) technique and the effect of using unconventional glass or ceramic seed is discussed. These fibers exhibit a unique micro and nanostructure made of veins dispersed in a single orientated Sr3Al2O6 crystalline matrix which has been thoroughly characterized by using electron backscatter diffraction (EBSD) and high-resolution transmission microscopy (HRTEM). The LHPG method also successfully produced optical fibers of 1 at% Er 3+-doped Sr3Al2O6. Even when other impurity was detected, the emission spectrum of the fiber presented sharp Er 3+ emission bands and long fluorescence lifetime values arising from the high crystalline structure perfection provided by the LHPG method.
