Latest Patents

Christodoulides' latest patents include innovative solutions for optical transmission links and fiber Raman amplifiers. The first patent, titled "Optical transmission link incorporating highpass optical filtering," describes an optical fiber transmission link designed to reduce channel depletion caused by stimulated Raman scattering. This is achieved by incorporating a high pass optical filter within the transmission fiber. The filter can consist of discrete components or be a distributed filter along the fiber's length. The cut-off frequency for this filter is strategically selected to be just below the frequency of the input channel being transmitted. In scenarios with multiple input channels, the cut-off frequency is adjusted to be immediately below the lowest input channel frequency.

The second patent, "Raman amplifier with gain enhancement from optical filtering," presents a fiber Raman amplifier that features increased gain and improved pump conversion efficiency. Similar to the first patent, this invention includes a high pass optical filter in the amplifier structure. The cut-off frequency for this filter is also chosen to be just below the frequency of the input signal that requires amplification. When multiple input signals are present, the cut-off frequency is controlled to be immediately below the lowest input signal frequency.
