Abstract
A polarization-maintaining (PM) optical fiber has a pure silica core surrounded by a cladding having a region with randomly arranged voids. Stress members are arranged in the cladding on opposite sides of and in line with the core, and impart birefringence to the PM optical fiber. The PM optical fiber is resistant to aging effects and has a broad single-mode spectral range of 400 nm to 1,600 nm.
