Abstract

A novel millimeter-wave generation method is proposed for frequency octupling using an integrated polarization division multiplexing dual-parallel Mach-Zehnder modulator (PDM-DPMZM) without an optical filter. The radio frequency spurious suppression ratio (RFSSR) of the frequency octupling scheme can be maintained above 30 dB over a wide range of modulation index (m ~ 2.87-5.0), which can increase the stability of the system. For verification, an 80 GHz millimeter wave with a radio frequency spurious suppression ratio (RFSSR) higher than 51.3 dB is generated from a 10 GHz radio frequency wave by simulation. Furthermore, the scheme is relatively simple and valuable due to no bias voltage may be controlled.
