Low Cost PAM-4 IM/DD Photonic-Layer Secured Communication for DCI Based on Phase Mask Academic Article uri icon


  • We demonstrate stealthy and encrypted IM/DD PAM-4 transmission where the signal is buried under ASE noise and coded with spectral phase mask. We report a considerable SNR gain which leads to error-free transmission despite negative OSNR.
