Reconfigurable optical transmitter

摘要

The present disclosure includes systems and techniques relating to reconfigurable optical transmitters. In some implementations, an apparatus, systems, or methods can include multiple ports to receive independent optical data signals or independent electrical signals that are converted into independent optical data signals, at least one optical pump laser, and one or more nonlinear optics elements configured and arranged to generate a phase conjugate for each of the independent optical data signals at least by combining the respective independent optical data signal with an output of the optical pump, and generate an output optical signal from the independent optical data signals at least by combining each of the independent optical data signals with its corresponding generated phase conjugate.

1. A method comprising:
receiving optical data signals having a first data order, wherein the received optical data signals have respective input frequencies that are different from each other; selecting from the received optical data signals a subset of optical data signals that has at least one but fewer than all of the received optical data signals; generating phase conjugates and copies of the selected optical data signals that have respective intermediate frequencies that are different from each other and from the input frequencies; and generating an output optical signal having a second data order higher than the first data order at least by combining at least the generated phase conjugates and copies of the selected optical data signals with remaining, non-selected one or more of the received optical data signals, wherein the generated output signal has an output frequency different from the input frequencies and from the intermediate frequencies.
