| Abstract(in English) | Optical transmitter devices are required that they satisfy a wide modulation bandwidth, a high optical output power, a high extinction ratio, a good optical waveform and a low dispersion penalty simultaneously. There was no report on an electroabsorption modulator (EAM), a semiconductor device useful for small-form-factor optical transmitters, which satisfied all of these requirements at 40 Gbps. In this report, improved performance of the 40-Gbps electroabsorption modulator (EAM) has been attained by employing (1) a semi-insulating substrate for reducing chip capacitance and (2) an asymmetric quantum well absorption layer which enables small-chirp operation under high optical output power conditions for the first time. In addition, (3) a modulator-driver IC has been packaged in a hermetically-sealed EAM module to prevent deterioration of frequency response by inserting coaxial cables and connectors. As a result, full compliance of the ITU-T G.693 specs (optical output power, eye-mask, extinction ratio, dispersion penalty) has been achieved. |
