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.

Optical Frequency Multiplication

A cost-effective novel method, Optical Frequency Multiplication using a Fabry Parot Interferometer (FPI), is demonstrated with Optisystem for generating micro/ millimeter signals optically and distributed to several remote located base stations. The simulation results show that the relative strength and frequency of the harmonics is strongly dependent on sweep frequency, FSR, Frequency Deviation and FM index. It is observed that optical uplifting of 150 Mbps AM radio signals to 11.8, 17.8 and 23.8 GHz frequencies corresponding to 4th, 6th and 8 th harmonic after transmission in optical downlink with the power level of 10 dbm, -10 dbm and -20 dbm respectively. Similarly, ASK data is recovered from the 4th harmonic of 12 GHz. To down-convert the uplink AM-RF signal of 5.8 GHz to a low IF of 200 MHz, 6 GHz high-frequency carrier generated by OFM is used, which is then sent back to the Central Station. QAM data at 550 MHz subcarrier is also recovered at CS successfully from 4th harmonic. Hence, the OFM system is used successfully for multiple functions concurrently, such as high-frequency-carrier-generation, optical signal transportation, frequency up-conversion, and bi-directional data transmission through generated harmonics.
