Abstract

We have developed electroabsorption modulated ridge waveguide-based DFB Lasers for 4x25Gbit/s that comply with the IEEE 100GBASE-ER4 Standard for 100Gbit-Ethernet. An identical InGaAlAs MQW layer stack is used in the DFB and the EAM section. Devices from a single wafer show excellent 25Gbit/s modulation performance at all four wavelengths with dynamic extinction ratios exceeding 9dB. All devices have facet output powers over +2.5dBm and are operated semi-cooled at 45°C.
