High-birefringent photonic crystal fiber [PDF]

OFC 2001. Optical Fiber Communication Conference and Exhibit. Technical Digest Postconference Edition (IEEE Cat. 01CH37171), 2001
A highly birefringent photonic crystal fiber design is analysed. Birefringence up to 10/sup -3/ is found. Random fluctuations in the cladding design are analysed, and the fiber is found to be a feasible polarization maintaining fiber.
