Abstract

A new refractive-index distribution for realising a single-polarisation single-mode optical fibre is proposed. This distribution features two pits, on either side of the core. The propagation characteristics are calculated by the two-dimensional finite-element method. The relative birefringence δβ/βav is 1 ∼ 2.5 × 10−4 when core/cladding index difference is 1%.
