Progress with the uncooled electroabsorption modulator integrated DFB laser

We have developed the uncooled electroabsorption modulator integrated distributed feedback (EA/DFB) lasers for small-footprint and low-power-consumption transceiver modulus. In this study, we used the temperature-tolerant InGaAlAs materials in EA modulator. We investigated the 10.7-Gbps, 40-km transmission performances over wide temperature range. The dynamic extinction ratio was 9.9 dB and 13.3 dB at the 10oC and 85oC. The modulated output power was more than +3.7 dBm even at 85oC. The long-term reliability was also investigated under APC condition at ambient temperature of 85oC with starting current of 120 mA. There was no significant degradation of the operation current up to 5000 hours. Uncooled 1300-nm range 25-Gbps and 43-Gbps EA/DFB lasers were also investigated. These devices will provide cost-effective 100-Gbps and 40-Gbps transceiver for next-generation high speed network system. A wide temperature ranged 12-km transmission with over 9.6-dB dynamic extinction ratio was demonstrated under 25-Gbps modulation. A 43-Gbps 10-km transmission was also demonstrated. The laser achieved clearly opened eye diagrams with dynamic extinction ratio of over 7-dB from 25oC to 85oC.
