Four-wave mixing based mid-span phase conjugation using slow light engineered chalcogenide and silicon photonic crystal waveguides

The goal of this paper is to demonstrate numerically, the mid span phase conjugation using slow light engineered 80 μm Chalcogenide PhC. Mid-span phase conjugation has significant advantages over other methods such as being independent of pulse shape, power, modulation format and bit-rate. We calculate the FWM efficiency for the various waveguides (3mm ridge (black dotted line), 80 μm Si PhC (blue line), and 80 μm Chalcogenide PhC (AMTIR) (red line)) when setting the pump wavelength in the middle of the flatband slow light window.
