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.

High birefringence single-polarization composite structured anti-resonant fiber
Results in Physics, 2023 We propose a highly birefringent, single-polarization composite structured anti-resonant fiber (CS-ARF). The proposed CS-ARF has an elliptical core, two symmetrically spaced arrays of elliptical air holes, and a six-tube anti-resonant structure.
