Abstract
A method and apparatus includes an optical source for a single order single-sideband suppressed-carrier optical signal with a bandwidth that scales from over 4 gigaHertz or is at least 8 GHz from an optical carrier frequency. In an example embodiment, an apparatus includes a stable laser source configured to output an optical carrier signal at a carrier frequency. The apparatus includes a radio frequency electrical source configured to output an electrical radio frequency signal with a radio frequency bandwidth less than one octave. The apparatus also includes an optical modulator configured to output an optical signal with the optical carrier signal modulated by the radio frequency signal in a plurality of orders (harmonics) of optical frequency sidebands. The apparatus further includes an optical filter configured to pass one single order optical frequency sideband of the optical signal, which sideband does not overlap the sideband of any other harmonic.
