Abstract :
The effect of optical reflection on direct modulated laser sources were experimentally studied. Key parameters of microwave optical links such as second and third order intercept point and spurious free dynamic range were measured as function of optical back-reflection level. MQW Fabry-Perot and DFB lasers were compared with short and long optical fibers.
