Abstract
Without the optical filter, a novel approach is designed for frequency 20-tupling photonic millimeter-wave generation based on four nested Mach-zehnder modulators (MZMs). Theoretical derivations and simulation verifications are demonstrated for the millimeter-wave frequency multiplication scheme. Optical sideband suppression ratio (OSSR) of 33 dB and radio frequency sideband suppression ratio (RFSSR) of 28 dB is achieved, respectively. Further, a 1.25 Gb/s data transmission performances are evaluated, the data signal could be transmitted 40 Km with the proposed scheme at BER = 10−9. The obtained results can assist with the design of high frequency radio over fiber (RoF) system.
