Abstract
In this paper, we have proposed and demonstrated an improved optical Millimeter Wave (MM-Wave) generation and a 2.5
Gb/s Radio over Fiber transmission using two cascaded Lithium Niobate Mach-Zehnder Modulators (LN-MZM) without any
filter. Both the MZMs are biased with symmetrical biasing parameters. By proper adjustment of RF amplitude, phase and
biasing parameters in the MZM, twelvefold MM-wave is generated. An unwanted optical sideband suppression ratio (OSSR)
higher than 37 dB and Radio frequency spurious sideband suppression ratio (RFSSR) higher than 37dB are achieved
without optical filters. Further, a 2.5 Gb/s data transmission performances are also simulated for both dual tone and single
tone modulation formats. The dispersion induced power penalty of 5 dB for the dual tone and 0.4 dB for single tone
modulation formats are obtained..
