Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object
Advanced Engineering Materials, EarlyView.We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

Automatic design of high-performance fiber-chip surface grating couplers based on Floquet-Bloch mode analysis [PDF]
, 2018 We propose a new strategy to automatically design highly efficient fiber-chip surface grating couplers. High performance designs are achieved with a substantially reduced computational cost by combining Floquet-Bloch mode analysis with a multi-objective ...

Sagnac interferometric switch utilizing Faraday rotation [PDF]
, 2009 In this paper, a novel fiber-based, magneto-optic switch based on a Sagnac interferometer is presented. Experimental results at 1550 nm are reported and device performance such as extinction ratio for both single-mode and multi-mode fiber is presented ...

Optics Express, 2018 Similar to coherent light passing through a scattering medium, the propagation of coherent light through a multi-mode fiber (MMF) will result in a random speckle field. For a non-polarization maintaining MMF, the randomization can be observed not only in

A Comparative Study of Few-Mode Fiber and Coupled-Core Multi-Core Fiber Transmission
Journal of Lightwave Technology, 2022 Few-mode fibers and coupled-core multi-core fibers are attractive transmission media for space-division multiplexed transmission systems as they enable a high spatial channel multiplicity whilst sustaining the current standard cladding diameter.

Highly multi-mode hollow core fibers
Optics ExpressThe loss and damage thresholds of conventional solid core fibers are greatly improved in anti-resonant hollow core fibers, but fabrication has largely been limited to single mode hollow fibers. There are many applications of conventional multi-mode fibers that would also benefit from the properties of hollow core fibers and are not currently addressed.

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response
Advanced Engineering Materials, EarlyView.A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

Super- and Anti-Principal Modes in Multi-Mode Waveguides
, 2017 We introduce a new type of states for light in multimode waveguides featuring strongly enhanced or reduced spectral correlations. Based on the experimentally measured multi-spectral transmission matrix of a multimode fiber, we generate a set of states ...

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Advanced Functional Materials, EarlyView.The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...
