Abstract
An optical fiber, comprising: (i) a rare earth doped silica based elongated core with a first refractive index (n) with an aspect ratio of 1:5 to 1; (ii) a silica based moat abutting and at least substantially surrounding the core, the moat having a refractive index n, wherein n<n; (iii) a silica based inner cladding surrounding the moat, the inner cladding having a third refractive index (n), wherein n>n; and n>n; (iv) a silica based outer cladding surrounding said inner cladding, the outer cladding having a fourth refractive index (n), such that n<n; the optical fiber exhibits single polarization at the operating wavelength band.
