Abstract
In accordance with various aspects of the disclosure, a method and apparatus is disclosed for increasing waveform bandwidth of an optical frequency waveform during optical double sideband suppressed carrier modulation. An optical modulator is configured to operate in double sideband, suppressed carrier modulation (DSB-SC) mode producing multiple optical sidebands and optical sideband harmonics. Proper selection of the appropriate optical harmonic via optical filter enables the synthesis of ultra-wideband single-sideband, suppressed carrier (SSB-SC) optical waveforms while simultaneously simplifying the radio frequency (RF) circuitry that generates the modulating radio frequency waveform.
