an optimal conversion gain equal to q6 dB, very close to the experimentally obtained value of 5 dB.
CONCLUSION
The generation of microwave signal mixing can be realized by FMrIM conversion by using all-optical components such as interferometers. An FP, an RR, and a UMZ have been investigated. The mixing conversion loss which can be obtained is better than the one obtainable with classical solutions of opticalแmicrowave mixing. The best conversion loss is the same with all types of interferometers, but better performances in terms of stability and frequency response are obtained when the transmission response of the interferometer is broadband over the microwave frequency range of interest. We have shown that the UMZ leads to the best compromise between good performance and practical realization. Experimental results obtained with a UMZ integrated on a glass substrate have proved to be in good agreement with simulation results, and have demonstrated the feasibility of this optical method for microwave mixing with a low-cost device of easy fabrication.
