Emergent nonlinear dynamics in photonic lattices
Since the discovery of dissipative Kerr solitons in optical microresonators, significant progress has been made in the understanding of the underlying physical principles from the fundamental side and generation of broadband coherent optical Kerr frequency ...
EPFL2024Resonators with tailored optical path by cascaded-mode conversions
Ileana-Cristina Benea-Chelmus, Marco Piccardo
Optical resonators enable the generation, manipulation, and storage of electromagnetic waves. The physics underlying their operation is determined by the interference of electromagnetic waves, giving rise to the resonance spectrum. This mechanism causes th ...
NATURE PORTFOLIO2023Time-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 York2023Improving the radiation characteristics of shorted annular ring antennas through symmetric aperture-coupled feeding
Anja Skrivervik, Hannes Bartle
In this paper, a novel feeding method for shorted annular ring (SAR) antennas is presented. SAR antennas can be designed to not excite surface waves and hence have desirable properties for many applications. The traditional method of feeding a SAR is throu ...
IEEE2023Accurate Measurement of Dynamic ON-Resistance in GaN Transistors at Steady-State
Elison de Nazareth Matioli, Hongkeng Zhu
Accurate characterization of the dynamic ON-resistance (RON) degradation is important to predict conduction losses for gallium nitride high-electron-mobility transistors (GaN HEMTs). However, even for the same device, many inconsistent results of dynamic R ...
2023Nonlinear dynamics and Kerr frequency comb formation in lattices of coupled microresonators
Tobias Kippenberg, Aleksandr Tusnin, Kenichi Komagata, Alexey Tikan
Recently, substantial progress has been made in the understanding of microresonators frequency combs based on dissipative Kerr solitons (DKSs). However, most of the studies have focused on the single-resonator level. Coupled resonator systems can open new ...
