Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
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 ...

Compliant, heterogeneously integrated micro-VCSELs [PDF]

, 2014
Vertical cavity surface emitting lasers (VCSELs) represent a ubiquitous light source with unique performance characteristics that excel edge-emitting lasers or light-emitting diodes. VCSELs are available, however, mostly on growth wafers in rigid, planar

Low‐Threshold and Broad‐Wavelength‐Tunable CsPbClxBr3‐x/SiO2/Ag Hybrid Cavity Plasmonic Nanolaser Operated at Room Temperature

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Precise and controllable laser wavelength modulation over a broad spectral range in nanoscale devices is pivotal for advancing next‐generation optoelectronic technologies. Herein, we synthesized high‐quality CsPbBr3 nanowires (NWs) via the anti‐solvent method and constructed a CsPbBr3/SiO2/Ag hybrid structure, demonstrating both photonic and ...

Efficient optoelectronic de-embedding for VCSEL intrinsic response extraction [PDF]

, 2010
In this present work, we propose a new method to remove the parasitics contribution to the VCSEL chip response,in order to obtain the intrinsic transmission behavior. It has been observed that the S11 reflection coefficient of the chip is only due to the
