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…
Electrically packaged silicon-organic hybrid (SOH) I/Q-modulator for 64 GBd operation
Heiner Zwickel, Juned N. Kemal, Clemens Kieninger +6
Silicon-organic hybrid (SOH) electro-optic (EO) modulators combine small footprint with low operating voltage and hence low power dissipation, thus lending themselves to on-chip in…
3D-Printed Optics for Wafer-Scale Probing
Mareike Trappen, Matthias Blaicher, Philipp-Immanuel Dietrich +5
Mass production of photonic integrated circuits requires high-throughput wafer-level testing. We demonstrate that optical probes equipped with 3D-printed elements allow for efficie…
Micro-lens array as tip-tilt sensor for single-mode fiber coupling
Philipp Hottinger, Robert J. Harris, Philipp-Immanuel Dietrich +8
We introduce a design for a tip-tilt sensor with integrated single-mode fiber coupling for use with the front-end prototype of the iLocater spectrograph at the Large Binocular Tele…
Demonstration of long-term thermally stable Silicon-Organic Hybrid Modulators at 85 °C
Clemens Kieninger, Yasar Kutuvantavida, Hiroki Miura +8
We report on the first demonstration of long-term thermally stable silicon-organic hybrid (SOH) modulators in accordance with Telcordia standards of high-temperature storage. The d…
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…
