Abstract
The multidisciplinary eld of Microwave-Photonics is at the convergence of photonic and
microwave or even wireless technologies. In this context, the processing, conversion and transmission of
microwaves, as well as high data rate digital and wireless signals, today use broadband optical techniques
with many applications. However, the frequency band available is frequently changing with up-to-date
commercial standards, and it is necessary to up- or down- convert the frequency of the electrical signals
using a suitable optical approach for mixing. This paper intends to give an overview on the optical
techniques used for frequency conversion, i.e. mixing, and gives the advantages and drawbacks of all
techniques presented.
