Raman Amplifier with Gain Enhancement from Optical Filtering (Technology #: 063000-01)

A fiber Raman amplifier with increased gain and improved pump conversion efficiency is formed by including a high pass optical filter in the amplifier structure. The filter may comprise one or more discrete components, or may be formed as a "distributed" filter along the length of the fiber amplifier. The cut-off frequency for the high pass optical...

Optical Transmission Link Incorporating Highpass Optical Filtering (Technology#: 082100-01)

An optical fiber transmission link with reduced channel depletion due to stimulated Raman scattering is formed by including a high pass optical filter in the transmission fiber. The filter may comprise one or more discrete components, or may be formed as a "distributed" filter along the length of the optical fiber. The cut-off frequency for the...
