Abstract :
Monolithically chain integrated semiconductor optical amplifiers and electroabsorption modulators are proposed and demonstrated in this paper. A high modulation extinction ratio of 21 dB in 3.5 V is measured, which mainly resulted from long waveguide structure. Results also show that the operation of SOA from 0-60 mA doesn´t degrade the extinction ratio with an optical gain of 7 dB.
