1.3µm SI-BH Electro-Absorption Modulated Laser Operating at 56Gbauds/s with 8.4dB Dynamic Extinction Ratio



We present a 56Gbaud/s 13μm electro-absorption modulated laser, based on semi-insulated buried waveguide technology. A dynamic extinction ratio of 8.4dB, with 1. 8dBm fiber coupled average power, and 112Gb/s PAM4 transmission, with a BER=10 -3 , are demonstrated.
