Abstract :
The world´s first monolithically integrated distributed feedback laser and electroabsorption (EA) modulator with an expected ges100 GHz -3 dBe bandwidth suitable for 100 Gb/s operation with on-off keying is presented. The design of the EA modulator uses a traveling-wave structure with three active segments and a total active length of 180 mum resulting in ~ 2.5 V peak-to-peak drive voltage for 10 dB optical extinction ratio and low electrical reflection.
