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 ...

Graphene Bragg gratings on microfiber

Optics Express, 2014
Graphene Bragg gratings (GBGs) on microfiber are proposed and investigated in this paper. Numerical analysis and simulated results show that the mode distribution, transmission loss, and central wavelength of the GBG are controllable by changing the diameter of the microfiber or the refractive index of graphene.
