A method of producing an optical waveguide by first forming a film of glass with a preselected index of refraction on the inside wall of a glass tube having a different preselected index of refraction. This glass tube and glass film combination is then drawn to reduce the cross-sectional area and to collapse the film of glass to form a fiber having a solid cross-sectional area; the core being formed from the glass film, and the cladding being formed from the glass tube.
