Two-level optical encryption is achieved, where a temporal delay between the signal and ASE carrier is used as the 1st encryption key. Code applied for optical spectral phase coding on the broad ASE is the 2nd key.

We demonstrate 60 Gbit/s transmission over 43-km SMF using low-coherence matched detection combined with spectral phase coding as two-layer optical encryption.
A block-ciphered (M-ary) optical code division multiplexing (OCDM) can provide larger security than a conventional OCDM system based on bit ciphering.
