Abstract

Burgeoning data rates are demanding a shift towards millimeter wave frequencies to combat the pressure on the congested spectrum that is in existence today. This paper elucidates how to generate a 160 GHz millimeter wave signal with a series parallel combination of polarization modulators (PolMs) using a frequency 16 tupling technique based on polarization property. A 160 GHz optical signal is produced by adjusting the phases between the PolM stages and selecting the right modulation index. Only marginal deviations in the optimally determined phase shift values cause minimal changes in sideband suppression ratios, according to research. At each level of the simulation, the outcomes are mathematically verified. The optical sideband suppression ratio (OSSR) and the radio frequency spurious suppression ratio (RFSSR) have been determined to be 65 and 51.4 dBm, respectively.
