Abstract
Over the past few years, high-speed optical transmission systems in the 10-Gbit/s range have reached a practical application level, utilizing monolithic integrated circuit technologies.1-3 To accomplish long-haul optical transmission over >100 km in such systems, there is a need for an external optical modulation method. This method, however, requires a large voltage swing, more than 3 Vp-p, for driving an optical modulator, such as an electroabsorption modulator. This paper describes a developed optical transmitter module, using a large voltage output DMT (doped-channel hetero-MISFET) modulator driver IC driving the electroabsorption modulator with high extinction ratio. Furthermore, a 10-Gbit/s, 140-km optical transmission experiment was successfully carried out, using the optical transmitter module and an optical receiver module, which contains a DMT preamplifier IC.
