Chip-Scale Watt-Range Terahertz Generation Based on Fast Transition in Nanoplasma Switches

Elison de Nazareth Matioli, Mohammad Rezaei

Despite recent advancements in photonics and electronics, there remains a lack of efficient, compact, high-power sources in the terahertz spectrum (0.3-10 THz). Recent research has revealed that nanoplasma (NP) switches can exhibit extremely fast transitio ...

Enabling Wide Bandwidth in Substrate-Integrated Waveguide Slot Antennas by Using Low-Index Metamaterials

Romain Christophe Rémy Fleury, Amir Jafargholi, Jalaledin Tayebpour

This paper presents a solution to overcome the inherently limited bandwidth of substrate-integrated waveguide (SIW) slot antennas. It is analytically shown that by decreasing the permittivity of a dielectric loaded slot antenna, the resulting bandwidth inc ...

500 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 ...
