Abstract

A novel scheme is proposed for frequency 12-tupling millimeter-wave generation based on two cascaded dual-parallel Mach–Zehnder modulators (DP-MZM) without optical filtering. The impact of imperfect extinction ratio (EXT) of each sub-MZM on optical sideband suppression ratio (OSSR) and RF spurious suppression ratio (RSSR) is investigated. Theoretical and simulation results show that the proposed scheme is feasible and system performance is insensitive to EXT when EXT is not less than 29 dB. Optical mm-wave with 26.4 dB OSSR and 20.3 dB RSSR can be obtained when the DPMZM is consisted of two sub-MZMs with 30 dB EXT. Furthermore, the system performance improvement through sub-MZM modulation index enhancement is analyzed.

Keywords: microwave photonics; frequency 12-tupling; Mach–Zehnder modulators; modulation index enhancement
