    "abstract": "We numerically study the possibilities for improved large-mode area endlessly\nsingle mode photonic crystal fibers for use in high-power delivery\napplications. By carefully choosing the optimal hole diameter we find that a\ntriangular core formed by three missing neighboring air holes considerably\nimproves the mode area and loss properties compared to the case with a core\nformed by one missing air hole. In a realized fiber we demonstrate an\nenhancement of the mode area by ~30 % without a corresponding increase in the\nattenuation.",
