  • Asymmetric direct detection of optical signals
    Patent number: 11799560
    Abstract: An asymmetric coherent receiver includes an optical front end configured to split a received optical signal into two paths, wherein the split received optical signal experiences a different optical transfer function in one of the two paths; two photodetectors each configured to detect power one of the split received optical signals in each of the two paths to obtain corresponding electrical signals; and circuitry configured to perform electrical domain extraction of information of each of the corresponding electrical signals from the two paths, wherein the different optical transfer function provides additional information utilized in optical field reconstruction via direct detection.
    Type: Grant
    Filed: January 19, 2022
    Date of Patent: October 24, 2023
    Assignee: Ciena Corporation
    Inventors: Xueyang Li, Maurice O'Sullivan, Zhenping Xing, David V. Plant, Mohammad E. Mousa Pasandi
