Abstract
We report 10 Gbit s-1 operation of an electroabsorption modulator (EAM) integrated with a distributed Bragg reflector (DBR) laser. The selective area growth technique was first employed in the 10 Gbit s-1 EAM fabrications to grow an active layer in the regions of the laser and the modulator. High side mode suppression ratios (SMSRs) over 45 dB and a 3 dB bandwidth of 12 GHz were observed. A clearly opened eye-diagram was also observed with 10 Gbit s-1 non-return to zero (NRZ) modulation signals. © 2005 IOP Publishing Ltd.
