Abstract
A transmitter for optical communication systems includes a source of optical radiation, a source of complex non-information signals, and a modulator unit in communication with the source of optical radiation. The modulator unit is also in communication with the source of complex non-information signals. The modulator has an input adapted to receive information-bearing signals.
Claims52
A transmitter for optical communication systems, comprising:
- a source of optical radiation;
- a source of complex non-information signals;
- and
- a modulator unit in communication with said source of optical radiation, in communication with said source of complex non-information signals, and further having an input adapted to receive information-bearing signals.

An optical communication system comprising:
- an optical transmission line;
- a transmitter in communication with said optical transmission line;
- and
- a receiver in communication with the optical transmission line,
- wherein the transmitter comprises:
- a source of optical radiation;
- a source of complex non-information signals;
- and
- a modulator unit in communication with said source of optical radiation, in communication with said source of complex non-information signals, and further having an input adapted to receive information-bearing signals.
6 more elements
A method of transmitting information in an optical communication system, comprising:
- generating a beam of light;
- modulating said beam of light responsive to a complex non-information signal;
- and
- modulating said beam of light responsive to an information signal,
- wherein said complex non-information signal has a first signal spectrum and said information signal has a second signal spectrum, said first and second signal spectra being substantially non-overlapping in a frequency domain.
