Calls to action and user engagement: The role of visual and verbal requests in nonprofit advocacy on Facebook

open access: yesComputers in Human Behavior Reports
A common strategy to boost user engagement on social media is to incorporate requests into posts. While previous research has focused on the effects of direct verbal requests (i.e., commands), the role of subtler, indirect verbal and visual requests ...

Inverse Optical Contrast in Metastable GeTe2: An Anomaly Enabling Low‐Loss Phase Change Photonics

open access: yesAdvanced Optical Materials, EarlyView.
An anomalous optical phase inversion in GeTe2$\mathrm{GeTe_{2}}$ provides a new platform for low‐loss non‐volatile integrated photonics at 1550 nm. The transition from the amorphous state (1) to a metastable vdW−GeTe2$\mathrm{vdW-GeTe_{2}}$ crystalline phase (2) is driven by bandgap widening, resulting in a negative refractive index change (Δn$\Delta ...

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Massively Degenerate Coherent Perfect Absorption in Gradient‐Index Fibers

open access: yesAdvanced Optical Materials, EarlyView.
A coherent perfect absorber (CPA) normally operates for only one or very few spatial modes. The CPA proposed here uses a gradient‐index (GRIN) fiber to absorb hundreds of spatial modes at once, its self‐imaging property replacing the bulky free‐space degenerate cavity of earlier designs. An analytic criterion sets how much modal degeneracy is required,
