Wireless Terahertz Communications: Optoelectronic Devices and Signal Processing

Harter, Tobias

Abstract (englisch):
Data transmission at carrier frequencies between 0.1 THz and 1 THz (T waves) has the potential to overcome the current limitations of wireless networks. The large carrier frequencies provide large data bandwidths, while the atmospheric attenuation is still sufficiently low. In laboratory experiments, data rates of more than 100 Gbit/s have already been shown. Widespread deployment of T-wave links in real systems, however, still requires novel signal processing schemes and device concepts that reduce the footprint, cost, and energy consumption of T-wave systems. T-waves occupy the spectral range between microwaves and near infrared. Advanced T-wave systems therefore allow to combine the advantages of both electronic and photonic signal processing schemes. In this context, efficient signal conversion between the various frequency ranges is essential. These goals are accomplished by chip-scale systems with low power consumption that can be realized in large quantities at low cost. Optoelectronic T-wave signal generation is already utilized in T-wave communication links and enabled record-high data rates. On the receiver side, the advantages of optoelectronic signal processing could not be shown yet. ... mehr
