Hybrid Electro-Optic Modulator Combining Silicon Photonic Slot Waveguides with High-k Radio-Frequency Slotlines
Sandeep Ummethala, Juned N. Kemal, Ahmed S. Alam +10
Electro-optic (EO) modulators rely on interaction of optical and electrical signals with second-order nonlinear media. For the optical signal, this interaction can be strongly enha…
Silicon-Organic Hybrid (SOH) Mach-Zehnder Modulators for 100 GBd PAM4 Signaling With Sub-1 dB Phase-Shifter Loss
Clemens Kieninger, Christoph Füllner, Heiner Zwickel +8
We report on compact and efficient silicon-organic hybrid (SOH) Mach-Zehnder modulators (MZM) with low phase shifter insertion loss of 0.7 dB. The 280 m-long phase shifters feat…
A verified equivalent-circuit model for slotwaveguide modulators
Heiner Zwickel, Stefan Singer, Clemens Kieninger +7
We formulate and experimentally validate an equivalent-circuit model based on distributed elements to describe the electric and electro-optic (EO) properties of travellingwave sili…
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…
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…
