Electronic Integrated Circuits
In fiber-optical communication systems the driver and control electronic for the electro-optical devices are becoming increasingly important to achieve lower power consumption and higher speed.
Co-designed optic and electronic devices are therefore a logical step to access additional optimization parameters to further improve performance.
These IC's will be designed in appropriate material systems like BiCMOS, CMOS or InP.
As an example, the IC-Design group developed a special, impedance engineered low power driver in BiCMOS technology, specifically adapted to the needs of our high speed InP based Mach-Zehnder- and IQ-Modulators.
With this approach a MZM driver with a low power consumption as low as 185 mW could be achieved for a bit rate of 32 Gbit/s OOK with a clear eye opening of more than 10 dB.
