      Hi everybody,
      I need to design a system for optical transmission of RF-OFDM signal such that the CSPR is close to 0 dB. It is given in the paper that it can be done via the dc bias voltage of MZM. I am using Lithium Niobate MZM.
      The main parameters of Lithium Niobate are
      —Switching bias voltage
      —Switching RF voltage
      —Bias voltage1
      —Bias voltage2.

      What voltage are the authors referring to by the term bias voltage? How do I measure it in optisystem?

      The optical carrier-to-sideband power ratio (CSPR) of an optically modulated millimeter-wave signal as the ratio of the optical power in the optical carrier to that of the first-order sideband, within a defined resolution bandwidth.

      Please help.
