Zusammenfassung:Presented is an electro-optical radiofrequency mixer based on a semiconductor optical amplifier directly modulated by an electrical local oscillator in the presence of an optical RF signal. A good conversion gain of about 5.7 dB and a low error vector magnitude below 3.8% were obtained for this mixer, proving its ability to achieve a frequency down conversion from 2.4 GHz to 100 MHz for an optical complex-modulated RF signal: QPSK, 16QAM and 64QAM.
