Abstract

A multiple wavelength light source and a method of constructing a multiple wavelength light source. The light source includes a plurality of light emitting diodes mounted to a substrate, located closely adjacent to one another. A single optical fiber is mounted to the substrate, appropriately positioned to provide a desired ratio of wavelengths at a desired amplitude.
