Fiber‐Endface‐Integrated PdSe2/2H‐MoTe2 Heterojunction Photodetector for Broadband Linear‐Polarization Detection

Advanced Materials Interfaces, EarlyView.
An all‐in‐fiber broadband polarization photodetector is demonstrated by integrating a PdSe2/2H‐MoTe2 van der Waals heterostructure onto a fiber endface. The device exhibits broadband response spanning 532 nm to 1630 nm, a fast response time of 59 µs, and a polarization ratio of 1.99. This work demonstrates a promising hardware strategy for polarization

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

Advanced Materials Technologies, EarlyView.
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 ...

Co-producing research with communities: emotions in community research

Global Discourse, 2020
In this article we explore the ways in which universities and communities can work together drawing on our experience of a community-university co-produced project called ‘Imagine’. We reflect on our different experiences of working together and affectively co-produce the article, drawing on a conversation we held together.
