In this article, we introduce a new approach to DSP-free coherent WDM for the DCI called FRESCO: FREquency Stabilized Coherent Optical Links for Low Energy DCIs.  ...  To overcome these limits, high capacity coherent WDM, traditionally relegated to the metro and long-haul networks, will need to move into the DCI.  ...  like carrier and phase recovery and avoid high power electronic mixers and digital circuits used in traditional OPLL and EPLL coherent receivers.  ...

In this letter, we propose a modulation classification algorithm which is based on the received signal's amplitude for coherent optical receivers.  ...  Results show that the proposed algorithm achieves accurate classification at optical signal-to-noise ratios of interest. Furthermore, it does not require carrier recovery.  ...  The MC algorithm is signal's amplitude-based, and thus, it does not require carrier recovery.  ...
