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…
Hardwire-Configurable Photonic Integrated Circuits Enabled by 3D Nano-Printing
Tobias Hoose, Matthias Blaicher, Juned Nassir Kemal +7
Photonic integrated circuits (PIC) currently rely on application-specific designs that are geared towards a particular functionality. Development of such application-specific PIC r…
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…
Coherent WDM transmission using quantum-dash mode-locked laser diodes as multi-wavelength source and local oscillator
Juned N. Kemal, Pablo Marin-Palomo, Vivek Panapakkam +8
Quantum-dash (QD) mode-locked laser diodes (MLLD) lend themselves as chip-scale frequency comb generators for highly scalable wavelength-division multiplexing (WDM) links in future…
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…
