Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

Optical Fiber Meta‐Tips Based on Partial‐Phase Control

open access: yesAdvanced Optical Materials, EarlyView.
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

open access: yesAdvanced Optical Materials, EarlyView.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.
