Claim:
1. A method of transmitting a multi-carrier optical signal, comprising: generating a single sideband signal representation of information to be transmitted, wherein the information to be transmitted includes multiple independent data channels; performing digital signal processing on the single sideband signal representation to generate a plurality of modulation signal components, wherein each modulation signal component is located either at the positive frequency or at the negative frequency; separating the plurality of modulation signal components into real-part and imaginary-part signals; modulating the real-part and imaginary-part signals onto a wavelength by using a single optical modulator to generate a modulated multi-carrier signal in an optical domain such that each carrier carries one of the multiple independent data channels; and transmitting the modulated multi-carrier signal to communicate the information to be transmitted.
