Spie-Int Soc Optical Engineering2024500 GHz field-resolved detection in thin-film lithium niobate devices
Ileana-Cristina Benea-Chelmus, Alessandro Tomasino
In this work, we show the coherent reconstruction of terahertz (THz) transients in thin-film lithium niobate integrated photonics circuits. Our devices modulate the intensity of a probe beam guided through a Mach-Zehnder interferometer (MZI) structure, und ...
New York2023Time-Domain Integration of Broadband Terahertz Pulses via Tapered Two-Wire Waveguide
In this work, we report on the implementation of a time-domain integrator device operating on arbitrary broadband Terahertz (THz) pulses. This analog signal-processing functionality is implemented by employing a two-wire waveguide (TWWG) variant, based on ...
New York2023Broadband spectroscopy and inelastic light scattering on the canted antiferromagnet hematite for antiferromagnetic magnonics
Collective spin excitations propagating in magnetically ordered materials are called spin waves (SWs) or magnons. They are promising for low-power and beyond-CMOS information processing, which do not suffer from the ohmic losses. SWs in ferromagnets (antif ...

Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Ido Kaminer, Simone Gargiulo, Francesco Barantani, Kangpeng Wang
The ultrafast dynamics of charge carriers in solids plays a pivotal role in emerging optoelectronics, photonics, energy harvesting, and quantum technology applications. However, the investigation and direct visualization of such nonequilibrium phenomena re ...
AMER CHEMICAL SOC2023Ultra-broadband terahertz radiation by supercontinuum generation and optical rectification in a dispersion-engineered waveguide: a numerical study
Ileana-Cristina Benea-Chelmus, Aleksei Gaier
In this work, we propose a numerical approach based on forward coupled mode modeling to simultaneously evaluate second- and third-order nonlinearities inside a dispersion-engineered waveguide towards the goal of generating broadband terahertz (THz) radiati ...
New York2023Induced giant piezoelectricity in centrosymmetric oxides
Paul Muralt, Dragan Damjanovic, Vasiliki Tileli, Mahmoud Hadad, Lukas Riemer, Daesung Park
Piezoelectrics are materials that linearly deform in response to an applied electric field. As a fundamental prerequisite, piezoelectric materials must have a noncentrosymmetric crystal structure. For more than a century, this has remained a major obstacle ...
2022Novel Search for High-Frequency Gravitational Waves with Low-Mass Axion Haloscopes
Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of external electric and magnetic fields. We discuss this phenomenon with a particular focus on reinterpreting the results of axion haloscopes based on lumped-element de ...
2022Integrated photonic circuits for terahertz applications
This talk will discuss recent advances in the nascent field of integrated photonic circuits for terahertz applications. This field explores photonic circuit technology to create miniaturized terahertz emitters and detectors by non-linear optical processes ...
IEEE2022Direct observation of multiband transport in magnonic Penrose quasicrystals via broadband and phase-resolved spectroscopy
Dirk Grundler, Sho Watanabe, Mohammad Hamdi, Vinayak Shantaram Bhat
Quasicrystals are aperiodically ordered structures with unconventional rotational symmetry. Their peculiar features have been explored in photonics to engineer bandgaps for light waves. Magnons (spin waves) are collective spin excitations in magnetically o ...
