Abstract
A single-mode elliptical core optical fiber (,) suitable for the transmission of solitons has a core aspect ratio that changes along the length of the fiber to provide a fiber dispersion that monotonically decreases along the fiber from one end thereof to the other. The fiber preform (,) is drawn from a draw blank (,) having a glass core (,) surrounded by cladding glass (,) and having apertures (,) that are diametrically opposed with respect to the core (,). The cross-sectional area of the void space within the apertures (,) varies with respect to the longitudinal distance along the apertures.
