Label‐Free Super‐Resolution Imaging Using Non‐Linear Exogenous Photon Avalanche Backlight

open access: yesAdvanced Science, EarlyView.
Transmission avalanche backlight (TAB) microscopy turns a photon‐avalanching Tm3+:LiYF4 crystal into a nonlinear luminescent backlight. Weak attenuation by a transparent sample is amplified into strong emission modulation: image contrast increases with sample attenuation and avalanche nonlinearity (N), while the effective point spread function narrows ...

Broadband Back-Short Transition From Waveguide to Thin Substrate-Integrated Waveguide in Multilayer Substrate in 270-GHz Band

open access: yesIEEE Journal of Microwaves
A broadband right-angle transition from a rectangular waveguide (RWG) to a substrate-integrated waveguide (SIW) with a small narrow-wall width is proposed in the 270 GHz band.

Robust NbN‐on‐Si/SiGe Hybrid Microwave Quantum Circuits With Long‐Term Stability

open access: yesAdvanced Electronic Materials, EarlyView.
Superconducting NbN resonators integrated with Si/SiGe quantum wells based semiconducting chip are investigated as a CMOS–compatible platform for scalable quantum hardware. Temperature–dependent microwave spectroscopy reveals loss mechanisms from TLS, quasiparticles, and scattering.
