  • System and method for the transmission of optical signals
    Patent number: 10659161
    Abstract: A system for transmission of an optical signal, the system including an optical coupler for splitting said signal into a first copy and a second copy. The optical coupler has an input for receiving the optical signal, a first output for the first copy and a second output for the second copy. The system also includes a first optical guide connected to the first output, a second optical guide connected to the second output and a superposition module for coherently superimposing the first copy and the second copy of the signal.
    Type: Grant
    Filed: September 24, 2018
    Date of Patent: May 19, 2020
    Assignee: ASTON UNIVERSITY
    Inventors: Filipe Ferreira, Naoise Mac-Suibhne, Andrew Ellis, Stylianos Sygletos, Mariia Sorokina, Christian Sanchez Costa
  • Mode division multiplexed passive optical network
    Patent number: 10193619
    Abstract: A method of compensating for crosstalk in a mode division multiplexing passive optical network using a technique of transmitter-side crosstalk pre-compensation, performed at the Central Office, in which a downlink reference signal such as a training sequence or pilot signal is retrieved at the transmitter without being influenced by crosstalk effects on its uplink transmission. An uplink reference signal is transmitted in a quasi-single mode transmission along the optical fiber, and a plurality of optical signals input to transmission multiplexer are adapted based on the uplink reference signal to pre-compensate for crosstalk.
