摘要

We have developed electroabsorption modulated DFB Lasers at 1305 nm using an identical InGaAlAs MQW core in the DFB and the EAM section. A 50Ω matching circuit is realized on-chip giving an f3dB of 39.4 GHz. We present 56 Gbit/s eyes with a dynamic extinction ratio of 9.5 dB. The fiber coupled output power under modulation is +5 dBm at 45°C.
