Abstract :
The linearity and link gain performance of analog fiber-optic links based on electroabsorption modulators operating at high optical power is analyzed. The negative feedback attributed to the photocurrent generation improves the modulator linearity at high optical power while causes the link gain to saturate. Potential schemes to improve both will be presented.
