    "abstract": "We report on a polarization maintaining large mode area photonic crystal\nfiber. Unlike, previous work on polarization maintaining photonic crystal\nfibers, birefringence is introduced using stress applying parts. This has\nallowed us to realize fibers, which are both single mode at any wavelength and\nhave a practically constant birefringence for any wavelength. The fibers\npresented in this work have mode field diameters from about 4 to 6.5 micron,\nand exhibit a typical birefringence of 1.5e-4.",
