Advances in Halide Perovskites for Photon Radiation Detectors
This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Q-factor and waveguide-sphere separation effects in waveguide-coupled microsphere resonators
Quality-factors of waveguide coupled microsphere resonators of 30µm diameter are measured. A Teflon buffer layer is deposited on the waveguide to separate the microsphere from the waveguide and the effect of this separation on the measured quality-factor

Generation of ultrashort electrical pulses in semiconductor waveguides [PDF]
We report a novel device capable of generating ultrashort electrical pulses on a coplanar waveguide (CPW) by means of optical rectification. The device consists of a completely passive GaAs-based optical waveguide, which is velocity matched to a CPW line.

Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Record Performance in Vertically Stacked, Solution‐Processed ZTO Schottky Diodes
Schottky diodes based on solution processed sustainable zinc—tin–oxide thin films present an eco‐friendly and versatile alternative to conventional CMOS based technologies. Beyond state‐of‐the‐art performance for vertically stacked solution‐based oxide diodes was achieved, including rectification ratios exceeding nine orders of magnitude, and intrinsic
