In the first quarter we have focused primarily on the amplitude-encoded link, distortion correction, and RIN transfer. We have experimentally analyzed the amplitude encoded link for gain and 3rd order distortion and are identifying the proper conditions for maximizing the overall spurious-free dynamic range SFDR of the link. In addition, we have investigated new methods for cascaded four-wave mixing FWM through a multi-stage nonlinear interaction. Finally, we are performing numerical simulations of the transfer of laser relative intensity noise RIN and quantum noise through the cascaded FWM process.
