Method, system and apparatus for optically transferring information

摘要

Information is optically transferred by generating an optical carrier signal having a first polarization state, generating an optical data signal separate from the optical carrier signal and having a second polarization state, matching the first polarization state and the second polarization state, combining the optical carrier signal with the optical data signal to create a combined optical signal, transferring the combined optical signal over an optical wave guide, and receiving the combined optical signal from the optical wave guide.
