A 40 Gbs/s monolithically cascaded integration of SOAs and EAMs is fabricated and demonstrated. Using cascaded SOA-integrated EAM, 20 dB high extinction ratio in 2.5 V, 13 dB optical gain is observed in such device. As low as -10 dB microwave reflection (DC to 35 GHz) is observed, leading to 40 GHz of -3 dB bandwidth and 40 Gb/s performance.
A novel monolithically integration of electroabsorption modulators (EAM) and semiconductor optical amplifiers (SOA) by chain structure is demonstrated. Chained SOA-Integrated EAMs with high-impedance-transmission-lines not only offers the performance of high extinction ration (> 20 dB) with gain, but also good microwave properties. Low reflection of <-12 dB (up to 30 GHz) and -3 dB electrical-to-optical...
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.
A detailed study of the nonlinearity and the spurious free dynamic range (SFDR) of a traveling-wave electroabsorption modulator is presented. A SFDR as high as 128dB-Hz/sup 4/5/achieved at 10 GHz.
