发明名称 ELLIPTICAL CORE FIBER WITH AXIALLY DECREASING ASPECT RATIO AND METHOD
摘要 A single-mode elliptical core optical fiber (15) 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 (30) is drawn from a draw blank (10) having a glass core (11) surrounded by cladding glass (12) and having apertures (13) that are diametrically opposed with respect to the core (11). The cross-sectional area of the void space within the apertures (13) varies with respect to the longitudinal distance along the apertures.
