Abstract :
For analog fiber optic links using electroabsorption modulators, the correlation between the RF link gain and the modulator photocurrent is investigated both theoretically and experimentally. Based on this correlation, a self-bias control scheme of the electroabsorption modulator for maximum RF link gain is proposed. This scheme can simplify the bias control of modulator arrays.
