Optical phase conjugation by an As2 S3 glass planar waveguide for dispersion-free transmission of WDM-DPSK signals over fiber
We report the first demonstration of optical phase conjugation (OPC) transmission of phase encoded and wavelength-division multiplexed (WDM) signals by the Kerr effect in a planar structured waveguide. The phase conjugated electric field of the signal is produced by four wave mixing pumped by a CW laser during co-propagating with the signal in a highly nonlinear waveguide fabricated in As2S3 glass. Experiments demonstrate the capability of the device to perform...[Show more]
