Abstract

Thirteen different single-mode optical fibers have been experimentally and theoretically characterized highlighting the influence of the core and cladding dopants on their Brillouin signatures: Brillouin spectrum, temperature, and strain coefficients. Tailoring the composition and the refractive index profile, optical fibers presenting Brillouin spectrum with multiple peaks have been designed, offering discrimination capabilities between the temperature and strain distributions along a single optical fiber.
