US 6,714,699 B1 · Multi-wavelength non-laser light source

Abstract

The present invention provides a method and system for providing a light source in an optical network. The method includes providing a multiple-wavelength light, and filtering the multiple-wavelength light into a plurality of separated wavelength bands for a plurality of channels. In the preferred embodiment, each of the separated wavelength bands is substantially centered about the wavelength of a respective one of a plurality of optical channels. The plurality of separated wavelength bands is stabilized and then provided to the optical network. The light source in accordance with the method and system of the present invention is designed to only output wavelengths that correspond to optical transmission channels while eliminating the rest. It suppresses possible mode hopping, thus maintaining the power stability of all channels. Since multiple wavelengths are provided in a single light source, the number of light sources required to service a network can be dramatically reduced, increasing efficiency and reducing the cost of equipment and time for maintenance as well.
