Compact Circuit Models for Nanoantenna-Based Lightwave Electronics
Adina Bechhofer, Felix Ritzkowsky, Karl K. Berggren +1
As the field of nanoscale lightwave electronics matures from centering around fundamental science to focusing on device engineering, there is a growing need for compact models that…
All-Optical Field-Resolved Spectroscopy With Interferometric Nonlinear Cross-Correlations
Felix Ritzkowsky, Gian Luca Dolso, Benjamin Mazur +2
Direct time-domain measurements of electric fields enable sub-cycle spectroscopy of light-matter interactions, but established techniques such as electro-optic sampling are constra…
Low peak-power pulse compression in gas-filled Herriott cells in the 2 μm wavelength range
Johann Gabriel Meyer, Felix Ritzkowsky, Fatemehsadat Ghaffari +5
At laser wavelengths longer than the prominent 1 μm range of high-power ytterbium-doped lasers, nonlinear phase shifts produced in nonlinear media for spectral broadening and subse…
Lightwave-Electronic Harmonic Frequency Mixing
Matthew Yeung, Lu-Ting Chou, Marco Turchetti +3
Electronic frequency mixers are fundamental building blocks of electronic systems. Harmonic frequency mixing in particular enables broadband electromagnetic signal analysis across…
Large Area Optical Frequency Detectors for Single-Shot Phase Readout
Felix Ritzkowsky, Matthew Yeung, Engjell Bebeti +9
Attosecond science has demonstrated that electrons can be controlled on the sub-cycle time scale of an optical wave, paving the way toward optical frequency electronics. Using cont…
PHz Electronic Device Design and Simulation for Waveguide-Integrated Carrier-Envelope Phase Detection
Dario Cattozzo Mor, Yujia Yang, Felix Ritzkowsky +4
Carrier-envelope phase (CEP) detection of ultrashort optical pulses and low-energy waveform field sampling have recently been demonstrated using direct time-domain methods that exp…
Ultrafast electron diffractometer with Terahertz-driven pulse compression

Terahertz (THz)-based electron manipulation has recently been shown to hold tremendous promise as a technology for manipulating and driving the next-generation of compact ultrafast…
Impact of DC bias on Weak Optical-Field-Driven Electron Emission in Nano-Vacuum-Gap Detectors
Marco Turchetti, Mina R. Bionta, Yujia Yang +5
In this work, we investigate multiphoton and optical-field tunneling emission from metallic surfaces with nanoscale vacuum gaps. Using time-dependent Schrodinger equation (TDSE) si…
On-chip sampling of optical fields with attosecond resolution
Mina R. Bionta, Felix Ritzkowsky, Marco Turchetti +6
Time-domain sampling of arbitrary electric fields with sub-cycle resolution enables a complete time-frequency analysis of a system's response to electromagnetic illumination. This…
