In this paper, we report on progress in design and fabrication of microstructured fibers made of phosphate glasses. The combination of microstructured large core fibers and very high solubility of rare-earth ions leads to improved performance of compact fiber lasers with single-frequency emission at power levels above 2 W. Microstructure-induced birefringence in active phosphate fibers is also demonstrated as well as the possibility of birefringence due to subwavelength dielectric structures inside the fiber core.
