Bit-rate flexible receive-side equalizer for multi-Gbit/s serial data links

The new receive equalizer topology permits to reduce the equalizer chip area by a factor of 5 to 10 and to cut down power consumption by half compared to common equalizers.

Data rates far in excess of 10 GBit/s can be achieved with the new structure.

Optical 8-level differential phase-shift keying (8-DPSK)

At the University of Stuttgart (Germany) a new method and device were developed, which demodulates optical signals with 3 bit information per signal with at the same time reduced technical complexity of the receiver.

 

 

Key Component for the Intergration of Electronic Data Processing and Optical Information Transmission

Seamless transition between electronic information processing and optical information transfer needs integration of fast optoelectronic components together with the associated electronic components (e.g. drivers, amplifiers, storage components, and microcontrollers) on the same substrate (e.g. silicon-on-insulator, SOI). The novel electro-optical component is based on the rapid change of transmission characteristics of an optical wave guide by means of the application of electric potentials.
