43Gb/s Operation of a Directly Connected Driver and Electroabsoption Modulated Laser for Low-Cost Packages

We demonstrate a 43 Gb/s InP-HBT driver directly connected to an Electroabsorption Modulated Laser with 2.2 Vpp amplitude and -0.7 to -3,5 V internally tunable offset. A high modulation sensitivity of the laser-modulator led to 8.3 dB extinction ratio.
