Millimeter wave generation through frequency 12-tupling using DP-polarization modulators

The polarization modulators are being utilized for the millimeter wave (MM-Wave) generation because of their bias drift free operation and high extinction ratio. In this work, an optical millimeter wave generation through frequency 12 tupling using dual parallel polarization modulator (DP-PolM) is demonstrated. By setting RF drive voltage and proper polarization angle of the DP-PolM, the frequency 12-tupled optical millimeter is generated with an optical sideband suppression ratio (OSSR) of 37.76 dB and radio frequency sideband suppression ratio (RFSSR) of 31.67 dB. A good agreement between simulation and theoretical approach is achieved. Further, impact of non ideal parameters on the OSSR, RFSSR and BER are also analysed and presented.
