A method of producing such a filter material which comprises heating a photochromic glass lens in a reducing atmosphere for a time and at a temperature that is sufficient to impart the recited characteristics to the glass surface and that is equivalent to a flowing hydrogen atmosphere, or immersing a tintable plastic solution in a dye solution for a time sufficient to impart the recited characteristics.

    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.
