Abstract

A method and device for bandwidth efficient multi-channel optical single sideband modulation with suppressed carrier and a corresponding method and apparatus for demodulation are disclosed. The modulator includes a bandwidth efficient coder/modulator, a Microwave/millimeter-wave upconverter and an OSSB modulator, an optical notch filter and a chirped fiber grating. The demodulator uses at least one narrowband optical bandpass filter in combination with at least one baseband optical receiver to recover the transmitted baseband digital signals. The modulation method and device are suitable for short or long-distance optical fiber transmission systems.
