Title:
A method and a device which compound the waveform which has the bandwidth of a super-broadband
Document Type and Number:
Japanese Patent JP6001105
Kind Code:
B2
Abstract:
In accordance with various aspects of the disclosure, a method and apparatus is disclosed for increasing waveform bandwidth of a radio 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 radio frequency waveform.
