Abstract
In this work, we propose a novel approach to generate high-quality optical millimeter-wave signals using frequency 12-tupling without an optical filter. The proposed approach is comprised of one dual parallel Mach- Zehnder modulators. The two sub-MZMs, biased at the maximum optical transmission point, which is only used for even-order optical harmonic generation, and introduces a phase shift on the optical output signal between the sub- MZMs. By properly adjusting the MZM biasing point, RF LO voltages and phases shift, sixth order optical sidebands only are generated which can result in 12-tupled mm-wave at the photo detector. Optical sideband suppression ratio (OSSR) higher than 37.65 dB and radio frequency spurious sideband suppression ratio (RFSSR) not less than 32.08 dB are achieved in this scheme. The performance of the signal in terms of OSSR and RFSSR is discussed, and the effects of non-ideal factors on OSSR and RFSSR are analyzed.
