Paper Abstract

Microwave photonic (MWP) based radio frequency (RF) channel is usually composed of three parts: microwave pre-processing part, electro-optical interconversion part and microwave post-processing part. The nonlinearity of active components causes serious harmonics at the output of MWP based RF channels. This paper mainly analyzes the harmonic distortions produced in the external-modulated optical transmission link and studies the variation of output harmonic power in the RF channel by changing the modulator bias point. According to the experiment, it is verified that the second harmonic can be effectively suppressed when the modulator is biased at high power point.
