Wireless THz link with optoelectronic transmitter and receiver
Tobias Harter, Sandeep Ummethala, Matthias Blaicher +15
Photonics might play a key role in future wireless communication systems that operate at THz carrier frequencies. A prime example is the generation of THz data streams by mixing op…
THz-to-Optical Conversion in Wireless Communications Using an Ultra-Broadband Plasmonic Modulator
Sandeep Ummethala, Tobias Harter, Kira Koehnle +14
Future wireless communication networks have to handle data rates of tens or even hundreds of Gbit/s per link, requiring carrier frequencies in the unallocated terahertz (THz) spect…
Silicon-plasmonic integrated circuits for terahertz signal generation and coherent detection
Tobias Harter, Sascha Muehlbrandt, Sandeep Ummethala +4
Optoelectronic signal processing offers great potential for generation and detection of ultra-broadband waveforms in the THz range, so-called T-waves. However, fabrication of the u…
Sub-cycle optical control of current in a semiconductor: from the multiphoton to the tunneling regime
Tim Paasch-Colberg, Stanislav Yu. Kruchinin, Özge Sağlam +10
Nonlinear interactions between ultrashort optical waveforms and solids can be used to induce and steer electric current on a femtosecond (fs) timescale, holding promise for electro…
