Paper Abstract

In this work we report the generation of microwave signals using photomixing of two diodes lasers. With this technique we can mix two optical signals that come from two different lasers. One laser is a single mode and the other laser is a multimode. Due to spectral separation between two lasers, microwave signals can be generated and tuned between 1 and 25 GHz. The bandwidth of the generated signal is approximately 2.5 GHz, however with the design and realization of microwave filters we can filter the photo generated signal and in this way, it is possible to obtain a radio frequency signal that can be used as a high frequency information carrier.
